@izzythepush,
Many people change, and most people have done daft things when young.
I'm not sure about Nige himself, but most commentators seem to think UKIP is just NF-lite.
I thought his speech yesterday sounded about right. However all the reporting today concentrates on loonies in the party.
I think it will shake down, and UKIP will become the third largest party soon. Immigration is such a hot topic, coupled with unemployment and stagnation.
