I'd vote for an Americanized version of UKIP in a moment -- certainly before I would vote for many of the current crop of "Republicans". I mean that, I understand the implications, and I do not apologize nor do I regret making such remarks.
The election results in Britain, France, and elsewhere in Western Europe illustrate that it remains possible for an upstart party to upstage the "established" parties.
It seems to be happening there.
I believe it could happen here, as well.
