A healer

Barack Obama, 2007:

"I think it is fair to say that I believe I can bring the country together more effectively than [Hillary Clinton] can," Obama said. "I will add, by the way, that is not entirely a problem of her making. Some of those battles in the '90s that she went through were the result of some pretty unfair attacks on the Clintons. But that history exists, and so, yes, I believe I can bring the country together in a way she cannot do. If I didn't believe that, I wouldn't be running."

Barack Obama, 2015:

President Barack Obama tore into Republican presidential candidates Monday night at a Democratic fundraising event in New York, saying their complaints about CNBC's debate moderation aren't an encouraging preview for their governing abilities.

"Have you noticed that everyone of these candidates say, 'Obama's weak. Putin's kicking sand in his face. When I talk to Putin, he's going to straighten out,'" Obama said, impersonating a refrain among Republican candidates that he's allowed Russian President Vladimir Putin too much leeway.

"Then it turns out they can't handle a bunch of CNBC moderators at the debate. Let me tell you, if you can't handle those guys, then I don't think the Chinese and the Russians are going to be too worried about you," Obama said.

Hope and change, baby!
