I think its hard to guage how much the Euroskeptic success in this election can actually be put down to Euroskepticism, and how much can be put down to general disillusionment with the political establishment.

On a side note, I think that's it for the Lib Dems, they've passed the point of no return. They lost all sense of meaning as a party when they entered the Tory coalition, and now they are feeling the consequences of that. The only way they can step back from the abyss is through a Labour-Lib Dem coalition come the general election. If that doesn't happen they are gone for good.
