What has happened to the Lib Dems?

Clegg and other Libdem cabinet members sold themselves to the devil. Cameron's no fool, he realised how popular Clegg had become in the run up to the elections and that he needed to destroy the trust the people had in him. Clegg is the head of the Libdem's, cut the head off of most things then the body will wither and die, this is being proven to be the case with the Libdem Party. Cameron would also drop them like a hot brick if he was certain that the Tories could win the next election outright. I don't expect Clegg to see out the year as the Libdem leader. There were rumblings before the election about a leadership challenge and rumblings of that sort tend to prove themselves correct.
