Farage is clever and knows how to tap into people with a strong sense of national pride; feelings driven by paranoia, fear and bigotry.
The name of the party is a stroke of genius - it has "UK" in it, and "UKIP" sounds snappy.
Farage is an expert at winning over the vote using lowest common denominator rhetoric and dubious soundbites/stats.
I can't see how the millions of voters he has onside are going to change their views. If anything, I think the party will become more popular on the back of this success. I'm not saying it will be enough to win a general election, but I think they now have a solid foothold in the electorate and it won't just evaporate or go away, in my opinion.
Section is right - abandon ship.
