John McCain on last night's debate and, in particular, Obama:

"I'm not embarrassed to tell you that I did not watch the Democrat debate last night," McCain said, "but I am told that Senator Obama made the statement that if Al Qaeda came back to Iraq after he withdraws -- after the American troops are withdrawn -- then he would send military troops back, if Al Qaeda established a military base in Iraq. I have some news: Al Qaeda is in Iraq. Al Qaeda, it's called Al Qaeda in Iraq, and my friends if we left they wouldn't be establishing a base, they wouldn't be establishing a base, they'd be taking a country. And I'm not going to allow that to happen my friends. I will not surrender. I will not surrender to Al Qaeda.

"It's pretty remarkable when Al Qaeda is in Iraq, and want to withdraw from Iraq and then say you will go back to Iraq if they have a base there. That's -- when you examine that statement it's pretty remarkable."

Obama responds:

"John McCain may like to say he wants to follow Osama bin Laden to the gates of Hell, but so far all he's done is follow George Bush into a misguided war in Iraq," he said.

Obama was responding, incredulously, to McCain's suggestion that he's unaware of the presence of Al Qaeda in Iraq, which the Arizona Senator said earlier today was apparently "news" to Obama at last night's debate.

"McCain thought that he could make a clever point by saying, 'Well let me give you some news, Barack, Al Qaeda is in Iraq,' like I wasn't reading the papers, like didn't know what was going on." Obama said, leaning into his developing McCain impression.

He then described the context -- a hypothetical question from Tim Russert -- and said, "First of all, I do know Al Qaeda is in Iraq, and that's why I said we should continue to strike Al Qaeda targets."

"I have some news for John McCain," Obama continued, "That's there was no Al Qaeda in Iraq until George Bush and John McCain" began the Iraq war, he said.

"They took their eye off the people who really were responsible for 9/11," he said.

Buckle up, folks. This is just the beginning.
