Will UKIP overtake the Lib Dems as Britain's 'third party'?

Possible in fact if the Lib Dems get AV it could be the opportunity for the likes of UKIP to push forward. I love to see EU loving Clegg and his cronies and muscular liberal Cameron's faces if the real conservatives got a load of seats and one day soon got government so we finally got a say on Britain being in the bloody EU.
