I think UKIP are Thatcherite. There is nothing that Farage says or does that could not have come out of her mouth. Economically Thatcherite and Socially Conservative along with isolationist on Foreign policy (but very pro-American).
The Tories currently have an identity crisis. Under Cameron they are Socially liberal (gay marriage etc) but economically more right wing than Thatcher (cuts, cuts, cuts, austerity, hating the poor, privatising things like the Post Office, even Thatcher dared not). If you look at the likes of Osborne, Cameron, Gove, Hunt et al they are not conservatives, in the truest sense of the word. The Orange book wing of the Lib Dems and the Cameroons are the same politically, whereas the SDP wing of the Lib Dems are essentially Labour. These types and Blairites believe in Liberal interventionism around the world, private sector solves everything blah blah blah.
The ironic thing for UKIP is that to actually have an electoral breakthrough, they need the very errr.......EUROPEAN!! Proportional Representation electoral system.
I had hoped the collapse of the Lib Dems would see the Greens have a UKIP-style breakthrough, or at least become more prominent. On energy, economic, social policy etc they are closer to my politics. They don't have any real supporters in the media though.
