What's the American right's problem with Kenya?

Mike Huckabee, who considers himself a serious Republican challenger for the 2012 American presidential election and who the media takes seriously (he's also host of a TV "news" show), made up facts about Barack Obama on a far-right radio show recently. This include that Obama "grew up" in Kenya with his father (this is patently false; he grew up with his mother, in Hawaii and Indonesia). Building on that lie, Huckabee added that Obama–while he was apparently growing up in Kenya–with his father supported the anti-colonial struggle against British colonialism. In contrast, "the average American" supports British colonialism. And I thought the America was born out of an anti-colonial struggle against British colonialism? The purpose with this baiting is that Huckabee is playing to a base for whom Kenya is equated with anti-American, i.e. not us, basically white America. There's tons of people debunking this nonsense daily in the US. (The clip above is from MSNBC's "The Last Word.") Anyway, though it deserves a longer post, I was wondering today how Kenya got this reputation in the US. Especially since independence its leaders were basically pro-US, anti-Communist and Kenya's government is a firm supporter of the US's War on Terror. (For the latter support Kenyans have even been targeted by Al Quada bombers.) I suppose at the heart of it is their hatred of Obama. He is not American after all, he has 'Kenyan tendencies'. Which are not American.
