The feeling is familiar. I had it four years ago and four years before that: a sinking feeling in the stomach. It's a kind of physical pessimism which says: "It's happening again. The Democrats are about to lose an election they should win - and it could not matter more."
If Sarah Palin defies the conventional wisdom that says elections are determined by the top of the ticket, and somehow wins this for McCain, what will be the reaction? Yes, blue-state America will go into mourning once again, feeling estranged in its own country. A generation of young Americans - who back Obama in big numbers - will turn cynical, concluding that politics doesn't work after all. And, most depressing, many African-Americans will decide that if even Barack Obama - with all his conspicuous gifts - could not win, then no black man can ever be elected president.
But what of the rest of the world? This is the reaction I fear most. For Obama has stirred an excitement around the globe unmatched by any American politician in living memory. Polling in Germany, France, Britain and Russia shows that Obama would win by whopping majorities, with the pattern repeated in Africa, Asia, the Middle East and Latin America. If November 4 were a global ballot, Obama would win it handsomely. If the free world could choose its leader, it would be Barack Obama.
