Something strange has happened in America in the nine months since Barack Obama was elected. It has best been summarized by the comedian Bill Maher: "The Democrats have moved to the right, and the Republicans have moved to a mental hospital."
The election of Obama - a black man with an anti-conservative message - as a successor to George W. Bush has scrambled the core American right's view of their country. In their gut, they saw the US as a white-skinned, right-wing nation forever shaped like Sarah Palin.
When this image was repudiated by a majority of Americans in a massive landslide, it simply didn't compute. How could this have happened? How could the cry of "Drill, baby, drill" have been beaten by a supposedly big government black guy? So a streak that has always been there in the American right's world-view - to deny reality, and argue against a demonic phantasm of their own creation - has swollen. Now it is all they can see.
Since Obama's rise, the US right has been skipping frantically from one fantasy to another, like a person in the throes of a mental breakdown. It started when they claimed he was a secret Muslim, and - at the same time - that he was a member of a black nationalist church that hated white people. Then, once these arguments were rejected and Obama won, they began to argue that he was born in Kenya and secretly smuggled into the United States as a baby, and the Hawaiian authorities conspired to fake his US birth certificate. So he is ineligible to rule and the office of President should pass to... the Republican runner-up, John McCain.
