This, sadly, is what the rest of the world sees when they view the mess that is the US.
Johann Hari, across the water at the UK's Independent has an incisive commentary, entitled Republicans, Religion and the Triumph of Unreason, with the subtitle How do they train themselves to be so impervious to reality?:
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.There's a lot more, so please take the time to read the whole thing.
These increasingly frenzied claims have become so detached from reality that they often seem like black comedy. The right-wing magazine US Investors' Daily claimed that if Stephen Hawking had been British, he would have been allowed to die at birth by its "socialist" healthcare system. Hawking responded with a polite cough that he is British, and "I wouldn't be here without the NHS".
This kind of mania can't be co-opted: it can only be overruled. Sometimes in politics you will have enemies, and they must be democratically defeated. The political system cannot be gummed up by a need to reach out to the maddest people or the greediest constituencies. There is no way to expand healthcare without angering Big Pharma and the Republicaloons. So be it. As Arianna Huffington put it, "It is as though, at the height of the civil rights movement, you thought you had to bring together Martin Luther King and George Wallace and make them agree. It's not how change happens."
