With Ed Balls being ousted that's 1 potential person out. Alan Johnson might have been tipped if it wasn't for his disastrous spell as Shadow Chancellor. Louise Ellman would be a good choice if it wasn't for her age. (I'm not sure she could commit to trying to get the PM job in 2020.) So do you go for a younger person like Luciana Berger who in 2020 will be similar in age to what Tony Blair was in 1997? Andy Burham could be a different option, as could Yvette Cooper. Any others? I think the worst high profile choices I can think of would be one of the Eagle sisters (they make too many gaffes), Diane Abbott (too controversial) or Hazel Blears. I also don't think Harriett Harman would be a good choice, she claims to want to make sure women are properly represented but she seems to be resented by a lot of women.
