Democratic commentator Howard Dean, the former Vermont governor who rose and fell quickly in the 2004 presidential race, sounded this morning like he thinks a college degree should be a prerequisite for holding the top job in the White House.

Dean said on MSNBC’s “Morning Joe” that Wisconsin Gov. Scott Walker’s three and a half years of college make him “unknowledgeable.”

Dean, also a former chairman of the Democratic National Committee, made the comment while disparaging Walker for declining to answer a question about evolution  from the BBC’s Justin Webb during an appearance at the Chatham House think tank in London while on a trade visit to the United Kingdom.

“I’m here to talk about trade, not to pontificate on other issues,” Walker told Webb. “I love the evolution of trade in Wisconsin, and I’d like to see an even bigger evolution as well.”

“Are you serious?” responded the show’s host, Joe Scarborough, sharply challenging Dean. “You’re saying he might not be qualified [for president] because he didn’t finish college?”

“I think there are going to be a lot of people who worry about that,” the Yale- and Columbia-educated Dean said.

Watch the clip to see how Scarborough rates a college degree—and how he takes Dean to school on the question, which appears to have become important in some quarters as Walker rises among his Republican peers in the polls.
