John Kerry has been trying to think like Mitt Romney as he stands in for the Republican nominee in presidential debate prep with Barack Obama. But in an interview on Tuesday, Kerry said it’s not easy to follow Romney’s train of thought on foreign policy.

“Romney has made clear that not only does he not have the judgment or vision’’ to be commander-in-chief, said the ’04 Democratic nominee, who chairs the Senate Foreign Relations Committee, “but he’s really been all over the map” on Afghanistan and more.

“I have trouble trying to figure out what his plan is, when he says things like ‘If I were president, Iran wouldn’t have a nuclear bomb.’ Well, guess what, Mitt Romney? They don’t and won’t.’’
