JON STEWART RIPS CHRIS MATTHEWS on the “I forgot Obama was black” bit. “Stewart seems to have cornered the market on ridiculing the Left in the American comedy world, mainly by default. Of course, Matthews makes himself an easy target — so easy, in fact, that many people on the Left seemed reluctant to come to his defense yesterday. If they’re tiring of Matthews’ schtick, MS-NBC may be left with nothing but Jesse Ventura fans … all three of them.”
