I'm not sure I agree with you that the majority of americans are far-right, tomba. Remember, the election system is not only broken and dominated by money and a skewed mainstream media, only about 50% of eligible voters turn out at all because they see they don't really have a choice. So, it wouldn't matter if you lived here and voted; you can vote for whoever you want, but we end up with the same thing anyway.
A majority of people in America are against US wars, in favor of single-payer healthcare, against radical capitalism and the wealth redistribution towards the top that went on in the last forty years. But the establishment is so strong, so corrupt, so vast that it creates its own little reality. I take issue with the fact that you mentioned Bush and Palin but not their twin, Obama. He is just as frightening and ruinous; because his policy is the same, regardless of his speeches. Giving Obama a pass makes you sound a bit like a right wing american yourself.
