Bob Murphy proposes:

I would like the pro-Obama people to come up with specific things that would make them admit they are mistaken right now, in their advocacy of Obama. For example, if Obama orders the use of nuclear weapons on Iran, surely that would count, right?

Er, yes. Jim Henley has made his list. Mine would include almost everything George W. Bush has already done. It couldn't get any worse, could it? I mean: no liberal Democrat could spend and borrow more than this Republican could he? Pretty close to impossible. And conservatives would go nuts - unlike their shameful indifference for last eight years.
