• The South Australian Liberals have suffered an embarrassing defeat at the hands of independent Geoff Brock in the Frome by-election following Saturday’s distribution of preferences. Crikey subscribers can read my post-mortem here, and a still lively discussion is raging on my live coverage post. The Advertiser reports that Brock’s success might give other potential independent candidates ideas, including “ALP stalwarts such as Rod Sawford and Murray Delaine”, who were respectively Labor members for the federal seat of Port Adelaide and the state seat of Cheltenham. Liberal leader Martin Hamilton-Smith says he is “ready to make deals with any independent candidate who ran next year in safe Labor seats such as Port Adelaide, Croydon, Lee and Colton”.

• Speculation about an early Queensland election continues to stop and start. Mark Bahnisch of Larvatus Prodeo says the Courier-Mail has damaged its credibility with its repeated wolf-crying on the subject, while The Australian’s D. D. McNicoll contends that “the whisper in Queensland political circles is Premier Anna Bligh will call the state election on February 28, a date that ensures bumper superannuation payouts for all the surviving members of the ALP’s ‘Class of 2001′ who were never expected to serve more than one term in parliament.” “Former Howard government senior adviser” David Moore surveys the landscape in The Australian.

• The NSW Nationals’ plans to select a candidate in a winnable seat for the 2011 state election by holding an open primary has caught the attention of blogger Tim Andrews, who is “unsure why this proposal hasn’t received more attention, as it has the potential to revolutionise Australian politics”. Ben Raue at The Tally Room reckons the idea is “at least a good gimmick”. The Nationals’ briefing paper on the subject can be read here.

• Western Australia’s daylight saving referendum will be held on May 16. Daylight saving was previously voted down in 1975 (53.66 per cent against), 1984 (54.35 per cent) and 1992 (53.14 per cent).

UPDATE: Graphic here. Rudd’s approval is down seven points to 63 per cent; Turnbull’s is down two to 45 per cent, his weakest result to date.

Elsewhere:

• Essential Research’s weekly survey has produced a status quo 59-41 result, along with a 56-20 preferred prime minister lead for Kevin Rudd that marks little shift from the previous time the question was asked in late November. Also featured are questions on expectations of the year ahead economically and for the Barack Obama presidency. Most interestingly, respondents were also asked to name their favourite prime minister since World War II, which produced a win for John Howard on 28 per cent. This is largely because those supporting Liberals (45 per cent of the total) showed no interest for contenders other than Howard and Bob Menzies (11 per cent), whereas the Labor loyalist vote was split between Kevin Rudd (20 per cent), Bob Hawke (12 per cent), Gough Whitlam (9 per cent) and Paul Keating (8 per cent).

• Former Tasmanian Tourism Minister Paula Wreidt has retired from politics, creating a vacancy in the electorate of Franklin that will be filled by a countback on February 2. This provides a clear entry to parliament for Daniel Hulme, the only remaining unelected Labor candidate from the 2006 election. My election guide entry tells me Hulme was an “Australian Taxation Office worker and former Young Labor president described by Sue Neales of The Mercury as a ‘right-wing pro-development campaigner’”. Hulme was the last man standing after Paul Lennon’s exit in the middle of last year resulted in the election of Ross Butler – who, according to Peter Tucker at Tasmanian Politics, has raised eyebrows with his performance. If Hulme declines to nominate, or if any further Labor vacancies arise in Franklin before the next election, we might see the unprecedented activation of the clause which would allow Labor to initiate a by-election rather than have the seat go to another party. Still more from Peter Tucker.

• More casual vacancy news: the last remaining Australian Democrats MP, South Australia’s Sandra Kanck, has been replaced following her retirement from her upper house seat by David Winderlich. More from Andrew Bartlett.

• The NSW Nationals have intriguingly announced they will preselect a candidate for a yet-to-be-determined winnable seat at the 2011 state election by conducting an American-style primary, open to all voters enrolled in the electorate. Peter van Onselen notes in The Australian that “parties in countries such as Britain and Italy have increasingly embraced primary contests, more often than not with electoral success to follow”. The most likely electorates for the trial are said to be Dubbo, Port Macquarie and Tamworth, each traditionally Nationals seats currently held by independents.

• Counting continues in South Australia’s Frome by-election, on which I have written an overview in today’s Crikey. Read about and comment on the progress of the count in the post below.
