Well 2015 been's the first election year I've actually followed (General Elections are the only ones that count IMO) and it's going to be pretty crap if we have Labour getting crushed at the may election losing their Shadow Chancellor and Foreign Secretary, and then going on to elect someone who is going to be the worse leader since well ever.
Tony Blair resigns and is replaced by:
Gordon Brown who is more to the left of Blair... who goes on to lose... who is then replaced by:
Ed Miliband who is more to the left of Brown... who goes on to lose... who is then replaced by:
Jeremy Corbyn who is more to the left of Miliband... who goes on to...
You can guess the rest I think
Obviously Brown was only very moderately more to the left of Blair but he was a more traditional tax and spend Labour right winger than "Third Way" Blair ever was.
I would only quibble with the Blair->Brown part. I think even if Blair led LAB in 2010 LAB would still have lost, mostly likely by greater margins. The internal civil war inside LAB if Blair stayed on would have guaranteed defeat no matter what. Not that Brown taking over stopped Blairites and Brownites from snipping at each other.
