What is important is not who won but what a battering the Tories took.
This would not be important if they had a big majority - but they do not.
If this continues and a few seats change hands in by-elections over the next couple of years the coalition could find themselves loosing the ability to defeat rebellions like the Student loan vote.
Once a party's rebels start to get a taste of power governing becomes difficult.
Clegeron will be hoping there are not going to be many marginal by-elections
