PRESIDENT MIKE GRAVEL JOINS LIBERTARIAN PARTY: Former Alaska Sen. Mike Gravel, who we still thought was running for the Democratic nomination for president, has joined the Libertarian Party and may run for president that way, too. Gravel is famous forthrowing rocks , yelling at other candidates, and this fantastic rapping video he made. Gravel's exit helps clear the way for a unified Democratic party under Barack Obama, so maybe that Hillary Clinton galoot should get her act together and do the same. [ The Trail ]
