Mr. McCain, I don’t care about an old washed up plumber, but we need to know the full extent of your relationship with Joe.

After all, he’s featured prominently in your debate and stump speeches, and is now invited to appear on tour with you. Arguably he’s way more involved in your campaign than William Ayers has been in Obama’s entire life. Further, he’s been better vetted and given more press interviews than your running mate. It’s only reasonable for us to assume he will feature in a McCain administration. How do we know he won’t wind up as Secretary of the Treasury? And we are right to be concerned because the last President who palled around with plumbers resigned in disgrace.
