UKIP has had 20 years, or as good as, to turn the Conservative Party into its own Eurosceptical fantasy of that party's past. It has failed miserably, and comments on certain websites make it perfectly clear that its supporters will now tell themselves anything in order to be able to go home to the federalist-as-ever "Tories" before they die.
Seats won is how we count these things in this country. UKIP has never won one. Not one. The Greens, also very anti-EU, have won one. Respect has won two, even if they have both been won by the same person, no friend of the EU. But UKIP has never even managed that. And for internal reasons, UKIP will be lucky to exist at all by 2015.
