Joe, I think you are being slightly disingenuous. A quick look through Mr Farage's interviews and statements on you tube should assure you that he is no extremist, on the right or on the left.
What makes you say such a thing without recourse to evidence?
Mr Farage opposes the EU on grounds of sovereignty ...the USA would never accept legislation from some other body which demanded that it accept unregulated immigration from overseas, so why do you think Mr Farage an extremist? He is actually an old "one nation conservative"

Don't believe all the media tell you Joe they may have ulterior motives :0)
