2009/10 UK Election with Blair as PM

[DC Al Fine]

Hard to say, but I suspect it wouldn't have been much different.  Blair had become very unpopular towards the end, but Brown was too by the time of the election, so I doubt there are that many people who voted Labour with Brown who wouldn't have done with Blair (and they'd probably have mostly voted Lib Dem or other rather than Tory).

I imagine moving 1-3% of the votes from Labour to Lib Dem would have some interesting affects for the Tories.
