What’s more:

• George Megalogenis of The Australian charts the rise of the centre left with reference to long-term Newspoll trends.

• Glenn Milne of The Australian has written a skeptically received article which speaks of plotting against Julie Bishop partly motivated by Senator Matthias Cormann’s designs on her blue-ribbon seat of Curtin. Andrew Bolt has published Cormann’s denial.

• Electoral Commissioner Ed Killesteyn advises the government to get hip by allowing voters to enrol online.

• Rick Wallace of The Australian notes the Victorian ALP is struggling to meet its affirmative action quota of 35 per cent female candidates in winnable seats, making it “almost imperative that a woman replaces a retiring woman, and that at least one in two of all retiring men are replaced by women”. While little action is expected ahead of the next federal election, speculation is said to surround the state seats of Craig Langdon (Ivanhoe), Peter Batchelor (Thomastown), Lynne Kosky (Altona) and John Pandazopoulos (Dandenong). More substantially, “former speaker Judy Maddigan has confirmed she will retire and she is expected to support former Labor staffer Natalie Sykes-Hutchins to replace her in the seat of Essendon”.

• Adelaide’s Independent Weekly reports on Malcolm Mackerras’s tip for next year’s state election: Labor to be comfortably returned, with the loss of only Norwood, Mawson and Light. The report notes something I had neglected to relate previously: SA Murray Irrigators Association chair Tim Whetstone was preselected in November as the Liberal candidate for Nationals MP Karlene Maywald’s seat of Chaffey, ahead of Citrus Growers of SA president Mark Chown and businessman Brian Barnett. Mackerras tips Whetstone to win.

• Ben Raue at The Tally Room has a post on whether the federal parliament should be enlarged, with reference to international practice.

• Possum notes the cubic polynomial distribution of two-party electorate results, and its implications for interpreting marginal seat exit polls.

Courtesy of the April edition of the invaluable Democratic Audit Update:

• The Joint Standing Committee on Electoral Matters will hold a “roundtable public hearing” on submissions to the green paper on campaign finance at Parliament House on Thursday, from 9.30am to 1pm.

• The Greens’ “parliamentary contract” with Labor’s minority government in the Australian Capital Territory is reviewed by Jenny Stewart in the Canberra Times.

• Brian Costar examines Electoral Commissioner Ed Killesteyn’s demolition of the spurious justifications for the Howard government’s 2005 electoral “reforms” at Inside Story.

• The Australian Parliamentary Library has published a research paper on the electoral demise of the Australian Democrats by Cathy Madden.

• Silly Steve Fielding joined with the Coalition on Wednesday to vote down government electoral reforms that would tie public funding for election candidates to their electoral expenditure, lower the threshold for disclosure of donations to $1000 from $10,000 (which the Howard government used its Senate majority to jack it up to), ban foreign donations and anonymous donations of over $50, and require parties to disclose donations every six months rather than annually. The sticking point is Fielding’s insistence that the government also arbitrarily cap public funding to political parties at $10 million. The bill was reintroduced to the House yesterday.

• Submissions have been published in response to the federal government’s green paper on donations, funding and expenditure.

• Responding to mounting speculation she will take on Don Randall in Canning at the next federal election, senior Gallop/Carpenter government minister Alannah MacTiernan tells The West Australian: “It’s something that I’d consider but it’s far too early. The election is a long way away and it’s not something a decision can be made on until early next year.”

• The South Australian Liberals have picked a new candidate for the state seat of Mawson to replace former Kingston MHR Kym Richardson, who was charged in December with attempting to pervert the course of justice by impersonating a police officer. Matthew Donovan, described by the local Southern Times Messenger newspaper as a “self-employed importer and property developer”, won preselection ahead of Heidi Harris, adviser to Shadow Transport Minister Duncan McFetridge and unsuccessful candidate for federal preselection in Mayo; Heidi Greaves, public servant, former Onkaparinga councillor and unsuccessful candidate for Elder; and Alana Sparrow, Housing Industry Association lawyer and former media adviser to Richardson.

• The Daily Telegraph reports that NSW Opposition Leader Barry O’Farrell “will hire a team of constitutional lawyers to explore recall provisions to end fixed four-year terms for incompetent governments”. This would involve provisions for the Governor to “sack a corrupt or useless government” if called on to do so by public petitions, presumably in a fashion similar to that which brought Arnold Schwarzenegger to power in California. UPDATE: More from a skeptical Imre Salusinszky at The Australian.

• Chris Back this week took his place in the Senate, filling the vacancy created by the departure of Western Australian Liberal Chris Ellison.
