I suspect the wear and tear of a non-stop campaign is starting to eat away at Barack Obama’s “nice guy” persona. Exhibit A:

Barack Obama told an audience here that, as president, he would use his position to promote higher education. “We’ve got a president who brags about ‘I was a C student, look at me. I got to be president and I can’t pronounce stupider.’ That’s not the message we want for the White House.”

Stay classy, Barack.
