Farage reminds me of Alex Salmond. Media savvy leaders with character and conviction- compare to the three clones of the major parties.
It should also be noted that Salmond was once in a similar position to Farage in that he led a minority party on the fringes of politics. 20 years on he's First Minister with a majority, (which was supposed to be impossible in the Scottish parliament) looking forward to an independence referendum (which thankfully he'll lose). Anyone who thinks UKIP is a flash in the pan should be mindful of the SNP. And I'd bet my house that %age wise more of the UK wants out of the EU than Scots want out of the UK (and into the EU).
To the OP anything that helps get rid of Cameron and have a proper right thinking government would get my vote. A Boris/Farage dream ticket?
