To be a pedant also, it is disputed whether the Liberal party still exists in its original form. The current Liberal Party says it is the continuation of the original but many say they are a new party since the original Liberals where dissolved when they merged with the traitorous SDP.
It's a common misconception that Clegg was unpopular, granted, among many students he was for a period of time, but in fact, Clegg has always been more popular than his party. His personal ratings were high in 2010, and they were a lot higher than the party's were in the run up to the last election. He was/is a decent speaker, a decent debater and came across as a fairly strong leader, whether you like him or not.
Tim Farron on the other hand, in my view, possesses next to no leadership qualities, every time I've seen him speak/debate I've just tended to roll my eyes at some half arsed populist, wishy washy jargon. Can see quite a slow death for the party with remaining held seats being eventually swallowed up by either of the two major parties. Just can't see Farron being able to inspire/excite anyone, or indeed come up with any respectable, sensible, policies.
