• Put a mark around Friday in your diaries as the day the Australian Electoral Commission is due to publish proposed boundaries for the federal redistribution in Queensland, which is gaining a thirtieth seat.

• Dennis Jensen, the Liberal member for Tangney, has been defeated in the local preselection vote by Glenn Piggott, from a field that also included Alcoa government relations manager Libby Lyons. The West Australian reports that Piggott won on the first round with the support of 20 branch delegates against 10 for Jensen and eight for “spoiler candidate” Libby Lyons (who unlike Piggott lives not locally but in the western suburbs, having earlier tried her hand at the state preselection for Nedlands). There is still the possibility that the result will be overturned by the party’s State Council on Saturday, as it was before the 2007 election when Jensen was initially defeated by Matt Brown. However, The West Australian report baldly states that Jensen “appears certain to lose his seat”. The only facts that gan be gleaned about Piggott from this remove is that he is a 52-year-old finance manager with Toyota.

• Another weekend preselection challenge proved to be a non-event when AMWU official and Geelong councillor Andy Richards withdrew from his tilt against Maria Vamvakinou in the safe Labor Melbourne seat of Calwell. Richards has attracted his fair share of critics: AMWU colleague Ian Jones launched a colourful spray quoted at length in The Australian, describing him as “dead wood” and “unsuitable for public office”, while federal MP Darren Cheeseman (whose electorate of Corangamite partly coincides with his council turf) made no effort to spare Richards’ feelings in a letter to Calwell preselectors. Beyond that, one can surmise that Richards’ withdrawal was influenced by peace deals between rival sub-factions of the Right, one of which was threatening to back Richards in defiance of a “stability pact” protecting the candidates of Left powerbroker Senator Kim Carr, among them Vamvakinou. Andrew Landeryou at vexNews reported last week that two state preselection challenges had been shelved under similar circumstances: Darebin councillor Tim Laurence dropped his bid to topple incumbent Steve Herbert in Eltham, and Fiona Richardson was spared a seemingly derisory challenge in Northcote from Kathleen Matthews-Ward, a Moreland councillor reportedly associated with the Right faction Shop Distributive and Allied Employees Association.

• Andrew Landeryou also reports that the state Liberal member for Sandringham, Murray Thompson, faces a preselection challenge from Margaret Fitzherbert. They are respectively said to be associated with the Peter Costello and Ted Baillieu factions.

• The Maribyrnong Leader reports youth worker Les Twentyman, who contested last year’s contentious Kororoit by-election, denies reports he will run against Labor member Marsha Thomson in Footscray, but says he will “look at” the possibility of running in an unspecified electorate if his health improves (he is “still recovering from surgery complications which threatened his life”).

• In case you missed it, George Megalogenis of The Australian provided the authoritative word last week on what an increased Labor majority at the next election might look like. Money quote:

Of the top 50 seats for tradesmen, 23 are marginal: 14 Liberal and nine Labor. A number of blue-collar Liberal seats proved hard to shift at the 2007 election, including Bowman and Herbert in Queensland, McEwen and La Trobe in Victoria and Macarthur and Paterson in NSW. All but Paterson had been solid Labor seats in the 1980s, swung to the Coalition in the 1990s because of the fallout from the last recession, and remained rusted on to the Howard government throughout the nation’s longest boom.

• I’ve added a thorough update to my ongoing post on Tasmania’s Pembroke upper house by-election.

• Another entry to the to-do list: a South Australian government proposal to reform the upper house through an end to staggered eight-year terms and a populist cut in numbers to below the point of effectiveness. This could be put to the voters at a referendum coinciding with the state election next March. However, legislation initiating the referendum will first have to pass the upper house itself.

• The Age reports Victorian Liberal deputy director Daniel Tehan has resigned his position to contest preselection for Wannon, to be vacated at the next election by David Hawker. Tehan is the son of the late Marie Tehan, who was among other things Health Minister in the Kennett government. His confirmed opponents will include Louise Staley, former state party vice-president and Institute of Public Affairs agriculture policy expert; Rod Nockles, Howard government adviser and runner-up in the recent preselection for the less desirable prospect of Corangamite; Elizabeth Matuschka, a University of Ballarat administrator who ran unsuccessfully in Ballarat at the 2004 federal election and for Ballarat City Council last November; Matt Makin, a Corangamite councillor; Katrina Rainsford, a Southern Grampians councillor; and Hugh Koch, whom the Warrnambool Standard tells us is a Southern Grampians tourism manager. David McKenzie of the Weekly Times reports that former Victorian Farmers Federation president Simon Ramsay, recently unsuccessful in bids for Corangamite and a position on the board of the National Farmers Federation, has decided against nominating and will instead seek a state upper house berth in Western Victoria. Andrew Landeryou at VexNews has also named as possibilities “complicated Costello loyalist” Georgie Crozier and former police sergeant and anti-corruption crusader Simon Illingworth. UPDATE: The Age says the closure of nominations has produced 10 candidates, which includes “company director Stephen Mitchell”.

• Nicholas McGowan, former adviser to state Opposition Leader Ted Baillieu, has put his hand up to succeed the outgoing Chris Pearce as the Liberal candidate for Aston. Also in the field are two Knox City councillors, Sue McMillan and Darren Pearce (respectively representing Dobson and Taylor wards). McMillan earlier stood for preselection in both Ferntree Gully and Monbulk ahead of the 2006 state election. The Knox Leader reports that former mayor Emanuele Cicciello “has been tipped to run but is remaining tight-lipped”. On July 1, the Herald Sun reported that names “yet to be confirmed” included “former Howard government adviser Alan Tudge and lawyer John Pesutto, who performed well in the recent Kooyong preselection battle”, but VexNews reports the latter assertion is “not correct”.

• Rick Wallace of The Australian reports that the preselection contest for Higgins is “being fought out between Kelly O’Dwyer, a former senior adviser to Mr Costello, and Institute of Public Affairs director Tim Wilson”, who respectively have the backing of the Kroger and Baillieu factions. Definitely out of the running are Institute of Public Affairs executive director John Roskam, Crosby Textor consultant Jason Aldworth and former state party director Julian Sheezel, which Andrew Landeryou at VexNews credits to gentle persuasion from Michael Kroger in support of O’Dwyer. No word lately on Tom Elliott, hedge fund manager and son of John.

• With Mal Brough frozen out of the running in Higgins and Aston, Andrew Landeryou at VexNews relates he is “apparently looking or waiting to be drafted”, which might yet occur when Fran Bailey vacates McEwen at the election after next (assuming she can hang on to her 27-vote margin).

• This weekend sees the local ALP preselection ballot take place for the safe Labor Melbourne seat of Calwell. Incumbent Maria Vamvakinou, a stalwart of Kim Carr’s sub-faction of the Left, faces a challenge from Andy Richards, Geelong councillor and official with the Left faction Australian Manufacturing Workers Union (metalworkers’ division). The ballot accounts for half the overall vote, the other half being determined by the party’s Public Office Selection Committee. According to Rick Wallace of The Australian, Richards could secure support from the Right faction National Union of Workers and Health Services Union – collectively known as the “Ambition Faction” – which forged alliances with the AMWU after being excluded from a “stability pact” between the Kim Carr Left and Bill Shorten and Stephen Conroy of the Right. Should this transpire, moves to heal the rift between the rival Right groupings could miscarry. Wallace reports that Richards also has support from “local Turks aligned with ALP identity and local councillor Burhan Yigit”. If support for Richards holds firm, Wallace says the decisive factors will be “local Kurds and a local Lebanese numbers man, Mohamad Abbouche”. As Andrew Landeryou of VexNews tells it, the former might be inclined to back Richards because they are angry that Kim Carr has failed to support Moreland councillor Enver Erdogan in the state preselection for Brunswick. Landeryou says the Ambition Faction is hopeful of securing as much as 60 per cent of the vote for Richards, but the Carr camp is “confident they’ll be able to snaffle at least 20 per cent of the vote back from pesky ethnic warlords who are pledged to support Richards”. UPDATE: See below.

• Nick Butterly of The West Australian says that while Dennis Jensen’s chances of surviving Saturday’s Liberal preselection ballot in Tangney have been boosted by the support of Malcolm Turnbull and “Perth business heavyweights”, Liberal insiders say he “still faces defeat in this Saturday’s ballot because of local concerns about his fundraising efforts and performance in Federal Parliament”. It is not stated which of his two opponents is considered the more formidable: Alcoa government relations manager Libby Lyons, or Toyota Finance executive Glenn Piggott. UPDATE: See below.

• The Launceston Examiner reports that the frontrunner for Liberal preselection in Bass, Brigadier Andrew Nikolic, has withdrawn citing family and work issues. The nomination is now likely to go to Steve Titmus, a former television newsreader.

• The Australian’s Strewth column is advised by a Liberal source that there is “absolutely no truth” to rumours Melanie Howard might contest preselection for Bennelong. Earlier reports suggested approaches to former state MPs Kerry Chikarovski and Andrew Tink had been rebuffed. Also mentioned a while back was former rugby union international Brett Papworth.

UPDATE (18/7/09): Via Frank Calabrese, we learn that ABC TV news in Perth reports that Glenn Piggott has defeated Dennis Jensen in the Tangney preselection vote. Remembering of course that Jensen also lost before the last election, only to have the result overturned on the intervention of John Howard. Meanwhile, Andrew Landeryou reports that Andy Richards has pulled out of the Calwell preselection, so there should be no problems now for Maria Vamvakinou – notwithstanding earlier reports that one Manfried Kriechbaum had also nominated as part of a campaign of mischief-making by state Keilor MP George Seitz.

• Arriving a day earlier than usual, Newspoll shows that the Coalition recovery detected a fortnight ago has come to a sudden end, with Labor’s lead back out from 53-47 to 56-44. The parties have also exchanged three points on the primary vote, Labor up to 44 per cent and the Coalition down to 37 per cent. However, the real shock is that Turnbull’s personal ratings have suffered what Shanahan calls “the single biggest fall in the survey’s 25-year history”: his approval rating has plunged from 44 per cent to 25 per cent, while his disapproval is up from 37 per cent to 58 per cent. Fifty-two per cent do not believe that John Grant received preferential treatment from the Prime Minister against only 24 per cent who do. Kevin Rudd’s lead as preferred prime minister is up from 57-25 to 65-18.

• ACNielsen, which is hopefully back to monthly polling as we enter the second half of the term, has Labor’s two-party lead up from 53-47 to 58-42. Labor’s primary vote is up two points to 46 per cent while the Coalition’s is down six to 37 per cent. Fifty-three per cent say the OzCar affair has left them with a less favourable impression of Malcolm Turnbull, whose approval is down 11 points to 32 per cent with his disapproval has shot up 13 points to 60 per cent. Turnbull comes third as preferred Liberal leader with 18 per cent, behind Peter Costello on 37 per cent and Joe Hockey on 21 per cent. Rudd’s lead as preferred prime minister is up from 64-28 to 66-25, and his approval rating is up three points to 67 per cent.

• Galaxy has Labor’s primary vote up a point to 44 per cent and the Coalition’s down two to 30 per cent. Sixty-one per cent believe Kevin Rudd has been open and honest about the OzCar affair, while 51 per cent “believed Mr Turnbull had been dishonest or somewhat deceitful”.

Once again, Victoria dominates the latest round of electoral news:

• The Joint Standing Committee on Electoral Matters has tabled two major reports which I haven’t got round to sinking my teeth into: the regular conduct of the federal election report, and that into the Commwealth Electoral (Above-the-Line Voting) Amendment Bill 2008.

• Rick Wallace of The Australian reports that complicated quarreling in the Victorian ALP has thrown up “rogue challengers” against at least ten state MPs. Keilor MP George Seitz, who faces enforced retirement in the wake of the Victorian Ombudsman’s report into Brimbank City Council, is said to be largely reponsible: Andrew Landeryou at VexNews identifies his state nominees as Tomislav Tomic (against Bundoora MP Colin Brooks), Seeralan Arumugam Gunaratnam (Carrum MP Jenny Lindell), Raymond Congreve (Lara MP John Eren), Rosa Mitrevski (Mill Park MP Lily D’Ambrosio), Philip Cassar (Mordialloc MP Janice Munt), Teodoro Tuason (Narre Warren North MP Luke Donnellan), Teresa Kiselis and Mate Barun (both taking on Northcote MP Fiona Richardson), Josefina Agustin (Prahran MP Tony Lupton), and Blagoja Bozinovski (Thomastown MP Peter Batchelor). For good measure, Seitz candidate Manfred Kriechbaum is taking on federal MP Maria Vamvakinou in Calwell. Other challengers are explained by Wallace in terms the “stability pact” forged between the Left and the Right forces associated with Bill Shorten and Steven Conroy, and counter-moves by rival Right unions seeking to forge ties with some of the more militant unions of the Left. This presumably accounts for Australian Manufacturing Workers Union candidate Andrew Richards joining the aforementioned Kriechbaum in a three-horse race against Vamvakinou in Calwell, Lisa Zanatta of the Construction Mining Forestry and Energy Union challenging Lynne Kosky in Altona, and Kathleen Matthews-Ward of the Shop Distributive and Allied Employees Association joining the Seitz challengers to Fiona Richardson in Northcote. The option of referring preselections to the party’s national executive remains available to John Brumby, who must be sorely tempted.

• Other challenges appear more obscure. A third Labor Unity candidate, Rick Garotti, is listed as a nominee against incumbent Craig Langdon in Ivanoe, in addition to the previously discussed Anthony Carbines. In Preston, Labor Unity MP Robin Scott is being challenged by Moreland councillor Anthony Helou (once of the Socialist Left, but more recently of Labor Unity) and Tamer Kairouz, said by Landeryou to be backed by upper house MP Nazih Elasmar, a principal of a Right sub-faction also linked with Theo Theophanous (not sure if any relation to Kororoit MP Marlene Kairouz). Two Socialist Left members are under challenge from factional colleagues, which Andrew Landeryou suggests can be put down to dealings between the Construction Forestry Mining and Energy Union and unions on the Right: Yuroke MP Liz Beattie faces a challenge from Colleen Gibbs, an official with the Australian Manufacturing Workers Union, while Darebin councillor Timothy Laurence has nominated against Steve Herbert in Eltham. Andrew Lappos, who in the past has been associated with the Left, is listed as a challenger to the Right’s Telmo Languiller in Derrimut, but it was reported last week that Languiller’s preselection had been secured by the national executive.

• The preselection contest for Brunswick has taken on new significance with the news that Phil Cleary will contest the seat as an independent. Cleary defeated the Labor candidate in the federal seat of Wills in the 1992 by-election that followed Bob Hawke’s retirement and was narrowly re-elected in 1993, before losing to Labor’s Kelvin Thomson in 1996. He has more recently worked for the Electrical Trades Union, which under the leadership of Dean Mighell has disaffiliated with the ALP and given support to the Greens. Three candidates are listed for Labor preselection, each a colleague of outgoing member Carlo Carli in the Socialist Left: Jane Garrett, Slater and Gordon lawyer and former adviser to Steve Bracks; Enver Erdogan, 23-year-old Moreland councillor and staffer to House of Represenatatives Speaker Harry Jenkins, said to be aligned with the Kim Carr sub-faction; and Alice Pryor, also a Moreland councillor, aligned with the rival Left sub-faction associated with federal Bruce MP Alan Griffin. Former party state secretary Eric Locke has proved a non-starter; Andrew Landeryou reports he has withdrawn in favour of Garrett, who would appear to be the front-runner. According to David Rood of The Age, Garrett also has the backing of John Brumby.

• Andrew Landeryou further reports that National Union of Workers state secretary Antony Thow has been “elected unopposed” for the third position on Labor’s Victorian Senate ticket. If that means what it appears to, it’s a significant story the mainstream media appears to have ignored, as Labor would seem very likely on current form to repeat its 2007 election feat of winning a third seat.

• The Moonee Valley Community News reports it is “not expected” that Victorian Planning Minister Justin Madden will be opposed in the Labor preselection for Essendon, to which the party has assigned him so sitting member South Eastern Metropolitan MLC Bob Smith can be given a safer seat in Western Metropolitan. Mark Kennedy, a former mayor of Moonee Valley, was earlier reported to have ambitions to replace the retiring Judy Maddigan.

• Federal Liberal MP Chris Pearce has announced he will not seek re-election in his Melbourne seat of Aston. Pearce gave his party a morale-boosting by-election win in the seat in July 2001, limiting the Labor swing to 3.7 per cent – which has since stood as exhibit A in the case that the Howard government’s re-election the following November could not entirely be put down to the subsequent Tampa episode and September 11. He was closely associated throughout his time in politics with Peter Costello, and the fact and timing of his departure have inevitably been linked to Costello’s shock announcement early last week. No discussion yet that I’m aware of as to who might replace him. Dennis Shanahan of The Australian reports that “another swathe of resignations” from federal Liberals is expected when New South Wales and Queensland redistributions are finalised early next year, although no names are named.

• The ABC reports that three Western Australian state Labor MPs, headed by the factionally unaligned Alannah MacTiernan, have moved at state conference for preselection reforms allowing “compulsory secret ballots for preselections, with delegates completing their own papers”.
