Barack Obama sure didn't shy away from the William Ayers/ACORN issue last night. He confronted McCain's smears head on, explaining the ridiculous guilt-by-association "connection" and denouncing them as petty, meaningless distractions.

In fact, Mr. Ayers has become the centerpiece of Sen. McCain's campaign over the last two or three weeks. This has been their primary focus. So let's get the record straight. [...]

Let me tell you who I associate with. On economic policy, I associate with Warren Buffett and former Fed Chairman Paul Volcker. If I'm interested in figuring out my foreign policy, I associate myself with my running mate, Joe Biden or with Dick Lugar, the Republican ranking member on the Senate Foreign Relations Committee, or General Jim Jones, the former supreme allied commander of NATO.

Those are the people, Democrats and Republicans, who have shaped my ideas and who will be surrounding me in the White House. And I think the fact that this has become such an important part of your campaign, Sen. McCain, says more about your campaign than it says about me.

Full transcript below the fold:

In fact, Mr. Ayers has become the centerpiece of Sen. McCain's campaign over the last two or three weeks. This has been their primary focus. So let's get the record straight. Bill Ayers is a professor of education in Chicago.

Forty years ago, when I was 8 years old, he engaged in despicable acts with a radical domestic group. I have roundly condemned those acts. Ten years ago he served and I served on a school reform board that was funded by one of Ronald Reagan's former ambassadors and close friends, Mr. Annenberg.

Other members on that board were the presidents of the University of Illinois, the president of Northwestern University, who happens to be a Republican, the president of The Chicago Tribune, a Republican- leaning newspaper.

Mr. Ayers is not involved in my campaign. He has never been involved in this campaign. And he will not advise me in the White House. So that's Mr. Ayers.

Now, with respect to ACORN, ACORN is a community organization. Apparently what they've done is they were paying people to go out and register folks, and apparently some of the people who were out there didn't really register people, they just filled out a bunch of names.

It had nothing to do with us. We were not involved. The only involvement I've had with ACORN was I represented them alongside the U.S. Justice Department in making Illinois implement a motor voter law that helped people get registered at DMVs.

Now, the reason I think that it's important to just get these facts out is because the allegation that Sen. McCain has continually made is that somehow my associations are troubling.

Let me tell you who I associate with. On economic policy, I associate with Warren Buffett and former Fed Chairman Paul Volcker. If I'm interested in figuring out my foreign policy, I associate myself with my running mate, Joe Biden or with Dick Lugar, the Republican ranking member on the Senate Foreign Relations Committee, or General Jim Jones, the former supreme allied commander of NATO.

Those are the people, Democrats and Republicans, who have shaped my ideas and who will be surrounding me in the White House. And I think the fact that this has become such an important part of your campaign, Sen. McCain, says more about your campaign than it says about me.
