"I do know libertarians who think Obama is the Antichrist, that he's farther left than John Kerry, much farther left than Bill Clinton, and you'd clearly have to be insane to vote for this guy," said David Boaz, executive vice president of the Cato Institute, a libertarian think tank. "But there are libertarians who say, 'Oh yeah? Do you think Obama will increase spending by $1 trillion, because that's what Republicans did over the past two presidential terms. So really, how much worse can he be?' And there are certainly libertarians who think Obama will be better on the war and on foreign policy, on executive power and on surveillance than McCain."
