Given how much more popular Farage is than Clegg, not surprising that he would edge it even if Clegg has walked all over him (which clearly did not happen), but encouraging for Farage that it was so close with Labour I'd say, even if Clegg's name is mud among such people he does represent closer to their view.

Both Clegg and Farage will have gained a few votes, but probably more for Clegg because he has more to gain.
