DES MOINES -- Obama said there was "no difference" between what he said about use of nuclear weapson and Clinton speaking on using them against Iran. Al Qaeda is in the mountains, everyone acknowledges that, Obama said.
This is part of the problem in politics, Obama said. We have gamesmanship and manufacture problems and differences.
Edwards first time to speak 15 minutes in. "How about a little hope and optimism," Edwards said. "Where did it go?"
Edwards said Musharraf is not a great leader, but he's stability. I think Sen. Obama's entitled to express his view. It's not shocking that Washington insiders would attack him. I think he adds something to this debate.
But he stopped short of completely tag teaming Clinton. He said we shouldn't talk about hypotheticals when it comes to nuclear weapons.
