Windsor's comments regarding the Libs being more likely to win in a re-election have been taken out of context (and were poorly worded originally).
I heard him explain his meaning last night which was: That a large number of the Liberal Party believed they had a better chance of winning a re-election (not Windsor), and were therefore keen to force a situation of back to the polls. Which would obviously result in a more unstable gov.
Personally I think the result would be much the same in a re-election.
