Interesting Scenario- I've never seen a roadmap of a 1994 election with both Brown and Blair, but the assumption is that Brown would probably win. The weird nature of the old Labour election system for leader divided up the section into three colleges- Trade Union/Members/MPs. Unless Blair could get more than 50% in the first round, the number of 2nd and 3rd preferences going to Brown would most likely sink Blair. Although Blair's asset was his support from the Shadow Cabinet/Media, meaning that Brown would be denied a base to run from
Basically 1994 could end up a lot like 2010- the least divisive candidate would win.
Answer wise- naturally Blair/Prescott.
I've heard that too. I actually believe I read somewhere that Blair and Brown made a deal where Brown wouldn't run for the party leadership and would support Blair in exchange for the position of Chancellor and Blair handing over the reins to him after two terms or so. I believe the general assumption is that Gordon Brown was more electable in a leadership contest but that Tony Blair was more electable in a general election (although I'd have to assume Gordon Brown would have won pretty easily in 1997 as well).
