I find the backlash against Clegg astonishing really, I think Lib Dems did a really good job of bringing balance to the previous 5 years. He conceded one issue and has been crucified for it which is bonkers.
It's not just the tuition fees thing though.
The Lib Dems stood for nothing and for nobody at this election. They're a traditionally left-wing party that suddenly decided they were as happy propping up a Tory government as a Labour one. That is a monumental error of strategy. I think Nick just assumed a lot of their supporters would vote for them anyway.
