The last thing the Liberal Democrats will want is to exit the coalition at this time. Repeating the kind of results they had in the local elections nationally would bring them incredible pain.
They have only themselves to blame, this is what happens when you try and be socialist in the north and free market in the south. If you are in the situation where you actually have the chance to be one way or the other you're in real trouble.
The party probably needs to look at where it's going and remember what
liberal actually means rather than pandering to the left of their party who seem to be more orange than yellow.
If they were to follow that course some more and genuinely be yellow I suspect they would find themselves appealing to many who feel that both Labour and the Tories are failing rather than trying to be orange or turquoise.
