McCain sort of can't win here.

Parnes reports from Minnesota:

A man in the audience stood up and told McCain he's "scared" of an Obama presidency and who he'd select for the Supreme Court.

"I have to tell you. Sen. Obama is a decent person and a person you don't have to be scared of as president of the United States," McCain said as the crowd booed and shouted "Come on, John!"

"If I didn't think I'd be a heck of a lot better, I wouldn't be running for president of the United States."
