How would you vote in U.K. party leadership elections?

[Slow Learner]

Conservative:

1965: Edward Heath. (I have a slight soft spot for him. Maudling wasn't terrible either iirc)
1975: James Prior. (Pretty good for a Tory. Heath had become bitter as feck by then and Whitelaw had...issues)
1989: ugh, Meyer. (Lesser of two evils premium example)
1990: Douglas Hurd. (Honestly kind of feel sorry for him. Made Heseltine look like Michael Caine)
1995: John Major.
1997: Kenneth Clarke. (Has become a git recently, but he's a good bloke overall. His deal with The Vulcan was very odd)
2001: Michael Portillo. (Post conversion obviously)
2003: ew. (*the night intensifies*)
2005: Kenneth Clarke. (poor field overall tbh)

Labour:

1955: Nye Bevan. (Uncertain vote, since he'd be crap as leader at that point)
1960: Harold Wilson. (Nothing against Gaitskell, but you can't Ill-son the Wilson)
1961: Anthony Greenwood. (Fairly interesting man, look him up)
1963: Harold Wilson. (Callaghan was fine, but Brown had err...issues)
1976: Jim Callaghan. (I like Foot more, but I honestly don't think he would've made a good leader. Crosland and Jenkins I would've been fine with)
1980: Peter Shore. (another interesting man)
1983: Peter Shore.
1988: Neil Kinnock. (Honestly, Benn was past it at that point)
1992: John Smith. (Not a perfect choice, but Gould was a bit out there)
1994: Margaret Beckett. (Might've been tempted by Blair)
2007: Gordon Brown. (I hold a lot of respect for him, and McDonnell is a prick)
2010: Ed Balls. (I have an odd love for him. Abbott and DMIL at the bottom obvs)
2015: Yvette Cooper.

Maudling wasn't terrible either iirc)

He was a massive, massive crook fwiw.

I am aware of that, yes.
