COOPER: And finally, "Keeping Them Honest," the moderator, me.

(BEGIN VIDEO CLIP)

COOPER: Congressman Bachmann, you also said at the last debate that everyone should pay something. Does that mean that you would raise taxes on the 47 percent of Americans who currently don't pay taxes?

(END VIDEO CLIP)

COOPER: I said it during the debate and the discussion afterwards, I was flat out wrong of course. What I knew and meant to say was 40 percent of Americans do not pay federal income tax. They do of course pay plenty of other state, local and federal taxes including federal payroll taxes, gasoline taxes and on and on. I made a mistake last night and I apologize.

I've got a lot of issues with CNN doing their best to be Fox-lite, but was glad to see Cooper do the right thing here and offer the correction.
