Who Was Responsible For McClurkin?

I don't think the use of an anti-gay Gospel singer on a muscial tour is a big deal. I don't believe it was done deliberately. Which means it was a staffer mistake. Here's one key test for the Obama campaign: has that staffer been fired yet? Who has been held responsible and fired for such an unforced error? If we are to be reassured that Obama can do what Bush can't: hold people responsible for mistakes, we need to know who did this and when they were let go.
