Barack Obama had the following to say last month at a Wisconsin Democratic Party Founders Day gala:

Obama would criticize McCain in a far less attractive manner, saying, "I am looking forward to a debate with John McCain. John McCain is a good man. He's an American hero. We honor his service to this nation. But he has made some bad choices about the company he keeps."

I don't think Obama's going to want to open up that subject in the general election.
