The McCain campaign is already referring to Joe Biden as Barack Obama’s mentor, and in his introduction of his new running mate, Obama seemed to agree. Obama forgot which person would run for which job, as you can see in his introduction of Biden at his rally in Springfield:

Let me introduce to you the next President … the next Vice-President of the United States of America … Joe Biden!

Well, maybe the reverse would make more sense, given Obama’s utter lack of experience. Obama himself just underscored the importance of experience by picking Biden. Hillary Clinton’s backers have a ready-made solution for Obama.

The question from this point will be which Democrat will make more gaffes from now until the election. So far. Obama’s up, 1-0.

Update (AP): Here’s the statement from Team Maverick:

“Barack Obama sounded as though he turned over the top spot on the ticket today to his new mentor, when he introduced Joe Biden as the next president. The reality is that nothing has changed since Joe Biden first made his assessment that Barack Obama is not ready to lead. He wasn’t ready then and he isn’t ready now.”

I realize both camps play the gaffe game, but for what it’s worth, I think the microscrutiny of each candidate’s statements is one of the most irritatingly juvenile aspects of the campaign, just a short step up from the nutroots psychoanalyzing McCain for racism based on the Britney ad. I wish we could get rid of it.
