I don't like or trust Farage particularly, I am uncertain how his policies could ever really translate on the whole but do agree with a few of his points. That being said though he had Clegg on the ropes for the entirety of the debate and came across very well, Nick Clegg stumbled, stumbled some more and then resorted to the same tactic from the general election debate of "where are you (audience member name x) - look at them and answer in a not at all convincing manner.
Clegg lost his mojo when he joined a coalition government and reneged on fundamental liberal policies and promises. Unfortunately for him, the shock performance he gave in the last big debate just looks forced and insincere.
In either case, no politician seems to be working for us in this day and age, it is all rhetoric.
