I find the people coming out bitching about Clegg talking to both parties a bit short sighted. He's playing everything out in the open, while also ensuring the best possible solution for the Lib Dems, himself, and in his view, the country. I believe they will only do a deal with the Conservatives, but by showing they have alternatives, they will get far more input to the cabinet - something which is valid if you view the number of votes cast and not the number of seats.
