More bad news for John McCain: Two quick, post-debate polls agree that Joe Biden was the better performer in his debate Thursday night with Sarah Palin.

-- CBS used uncommitted voters, who gave Biden the edge in early numbers, 46-21 percent, over Palin.

-- CNN's instant poll of regular voters showed Biden victorious, 51-36.

More polls will be released early Friday. But they will likely show most Americans were not impressed with Palin's performance in her one and only debate with Biden.

That news is not going to help McCain. He was counting on Palin at least holding her own with Biden Thursday night. And she didn't.
