John McCain is looking in the eyes of Barack Obama, seeing if he can flap him.

“I’m not President Bush. If you wanted to run against President Bush, you should have run four years ago.”

A little later he said that Obama had outright lied about McCain’s policies.

He has had some aggressive moments so far, and has forced Obama to explain his connections with Bill Ayers and ACORN. He also made sure he wasn’t sheepish about his supporters or Gov. Sarah Palin, both of whom have been under scrutiny in the media.

Some words are appearing that haven’t much in debates, with the exception of the candidates’ discussions with Rick Warren in August: immigration, stem cell research…but so far they haven’t really talked about them.

I think Bob Schieffer is doing a good job.
