John Bolton, the former U.S. ambassador to the UN under George W. Bush, was asked on Fox News Wednesday whether he would seek the GOP nomination for president in 2012. Bolton replied, "I'm not saying no." On MSNBC last night, Chris Matthews could barely keep a straight face when talk turned to Bolton's non-denial. "This guy," chuckled Matthews, "is the super hawk of all time." In his defense, Matthews showed a lot of restraint by not playing the mustache card.
