• 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”.

In other news, it’s all happening in Victoria:

• Peter Costello’s surprise announcement that he will not contest the next election has raised the flag on another epic Victorian Liberal preselection stoush in his Melbourne seat of Higgins, which housed successive Liberal prime ministers in Harold Holt and John Gorton. Furthermore, Costello has raised the possibility of an early departure and a by-election, “if it’s in the party’s interest”. Immediately prior to Costello’s announcement, Institute of Public Affairs executive director John Roskam signalled his intention to run if Costello stood aside, after earlier testing the waters in Kooyong (see below). However, Peter van Onselen in The Australian reports that Costello has resolved to oppose Roskam due to equivocal comments he made to David Penberthy of The Punch about Costello’s future value in politics. Van Onselen further reports widespread displeasure at this and other remarks seen to be in breach of Liberal rules that preselection aspirations are not to be discussed with the media. Costello reportedly wishes for the seat to go to a former staffer, Kelly O’Dwyer. It had earlier been reported that O’Dwyer might depose incumbent Ted Baillieu loyalist Andrew McIntosh in the state seat of Kew. The other big name in the Higgins mix is Mal Brough, who has moved to Melbourne and is said to be hopeful of a return to politics that doesn’t involve further dirtying his hands in the morass of the Queensland Liberal National Party. However, Phillip Coorey of the Sydney Morning Herald reports party sources say he has “no chance”. Also mentioned are former state party director Julian Sheezel, who was said to be backed by Costello but opposed by Michael Kroger when talk of Costello’s departure was in the air after the election, Jason Aldworth, a former banking colleague of Michael Kroger and more recently a consultant for Crosby Textor; and, intriguingly, Tom Elliott, hedge fund manager and son of John, who memorably sought to depose Roger Shipton as member for this very seat in pursuit of his prime ministerial ambitions.

• Merchant banker Josh Frydenberg has won the hotly contested preselection to succeed Petro Georgiou as the Liberal candidate for Kooyong. Andrew Landeryou at VexNews reports that Frydenberg won the second round ballot over industrial relations lawyer John Pesutto by 283 votes to 239 after all other contenders were excluded in the first round. The result is a defeat for Ted Baillieu, whose power base had pursued various stratagems designed to thwart Frydenberg, the preferred candidate of the rival Kroger faction.

• The ALP national executive’s role in Victorian state preselections has been further expanded following John Brumby’s decision to refer to the body all state upper house preselections for next year’s election. Labor insiders quoted by David Rood of The Age relate that the decision will “all but end” the career of Theo Theophanous, who faces a vigorously contested rape charge and was recently among those named adversely in the state Ombudsman’s report into Brimbank City Council. This week the national executive acted as expected in relation to a number of lower house preselections referred to it in the wake of the latter imbroglio, selecting former Trades Hall Council deputy secretary (and wife of New South Wales Senator Steve Hutchins) Natalie Sykes-Hutchins to replace George Seitz in Keilor and confirming incumbents Telmo Languiller, Rob Hulls, Marsha Thomson and Marlene Kairouz in Derrimut, Niddrie, Footscray and Kororoit. It has also been confirmed that Victorian Planning Minister Justin Madden will seek to move to the lower house by nominating for preselection in Essendon, to be vacated by the retiring Judy Maddigan. In his absence, the national executive has chosen incumbents Martin Pakula, Khalil Eideh and Bob Smith to head the ticket in Western Metropolitan (Smith currently represents South-Eastern Metropolitan).

• Helen Shardey, Victorian Shadow Health Minister and member for Caulfield, has indicated she will stand down at the next election. It had been reported she faced a preselection challenge from David Southwick, previously unsuccessful in the federal seat of Melbourne Ports in 2004 and for the state upper house Southern Metropolitan in 2006.

• Andrew Landeryou at VexNews reports that former Liberal MP Phil Barresi, whom he describes as a “factionally unenthusiastic Krogerite”, has been given the green light to attempt to recover the seat of Deakin which he held from 1996 until his defeat in 2007. Barresi reportedly won on the first round over eccentric perennial Ken Aldred, who was dumped in favour of Barresi in 1996 after peddling weird conspiracy theories, and one Deanne Rhyll. Perhaps Barresi is encouraged by the precedent of 1984, when the Liberals unexpectedly recovered the seat (with some help from a redistribution) after losing it when the Hawke government was elected in 1983.

Elsewhere:

• Glenn Milne in The Australian reports on the Labor succession in the federal seat of Macquarie, which will be vacated at the next election by Bob Debus. As Milne tells it, Debus or his supporters put it about that his recent decision to withdraw from the ministry and bow out at the next election, which helped the Prime Minister no end as he sought to construct a new cabinet in the wake of Joel Fitzgibbon’s resignation, was conditional upon Debus being given the right to anoint his own successor. This was hotly disputed by Right powerbrokers who are bitterly opposed to Debus’s objective of freezing out industrial barrister Adam Searle, a Left faction colleague but personal rival.

• Two new goodies from Antony Green. An extensive paper for the New South Wales Parliamentary Library provides all manner of detail on the state’s Legislative Council election in 2007, while an accompanying blog post scrutinises the performance of the optional preferential above-the-line voting system introduced after the 1999 election produced a tablecloth-sized ballot paper and elected candidates from groupings that would be flattered by the “micro-party” designation. He further discusses the potential for such a system to resolve the issues which saw Steve Fielding elected to the Senate in 2004. For the more casual election enthusiast, a new 2010federal election calculator allows you set the two-party result to taste to find out the seat outcome in the event of a uniform swing. It turns out a 50-50 result would give the Coalition exactly half the seats and presumably allow it to govern with support of the three independents. Labor loses its majority at 50.8 per cent.

• Queensland independent MP Peter Wellington has introduced a private member’s bill providing for fixed three-year terms, with an escape clause if a new government cannot be formed in the wake of no-confidence motion and a provision allowing for a five-week postponement if there is a clash with a federal election or a “widespread natural disaster”. The major parties both support fixed four-year terms, which unlike Wellington’s proposal would require a referendum. Negotiations for such a referendum broke down last year when then Opposition Leader Lawrence Springborg insisted on further unrelated reforms, but his successor John-Paul Langbroek has foreshadowed a more “flexible” approach in future discussions with the government.

• Christian Kerr of The Australian evaluates the Australian political blogosphere.

UPDATE: Thanks to Rebecca in comments for bringing my attention to the fact that Allison Ritchie, Labor member for the Tasmanian Legislative Council district of Pembroke, yesterday announced she would quit parliament after enduring a storm of controversy over her appointment of family members on her staff. This will presumably result in a by-election shortly in Pembroke, where Ritchie defeated an independent incumbent in 2001 and won re-election in 2007. The Electoral Act allows the government enormous latitude on the timing of such a by-election, so I’ll hold off on giving it its own post until its intentions become clearer. Ritchie claims to have been the victim of a plot from within her own party, which presumably explains why she has decided to go now rather than wait for the more convenient juncture of early next year, when a by-election could be held with the state election in March or the annual periodical upper house elections in May.
