Is there some kind of competition on the left to see who can make the most denigrating remark about the mental acuity of Republicans?  As we've noted, last night Paul Begala called President Bush "a high-functioning moron," perhaps his bid to one-up Rep. Charles Rangel, who had called Sara Palin "disabled."

Today, it's Jonathan Capehart's turn.  Speaking with David Shuster on MSNBC this afternoon, the Washington Post editorial writer said that Sarah Palin reminds him of Lauren Caitlin Upton, the 2007 Miss Teen South Carolina whose tangles ["U.S. Americans," etc.] with the English language made her an overnight YouTube star.

Capehart's comment came in response to a Shuster inquiry about Palin's reply to Katie Couric's question about the relevance to Palin's foreign-policy credentials of Russia's proximity to Alaska.
