2012 Ramsay state by-election

A by-election occurred in the South Australian House of Assembly seat of Ramsay on 11 February 2012.

The by-election was triggered by the resignation of former premier and state Labor MHA Mike Rann.

On two-party preferred margins of 18.0 percent and 12.8 percent from the 2010 election, considered safe margins on the previous pendulum, Labor would have likely retained both seats on the two-party preferred vote based on unchanged statewide Newspoll since the previous election.

Rann stepped down in favour of Jay Weatherill as party leader and premier in 2011.

[8][16] Labor retained the seat on a 66.7 percent two-candidate preferred vote against Aldridge, with a majority in all nine polling places – Ramsay remained the safest Labor seat in the parliament.
