President Obama’s Oval Office speech Tuesday marked the end of an era — an era in which at least half the population believed any crisis could be defused by one man’s supposed rhetorical genius and personal charisma. The derisive reception of President Obama’s Tuesday night speech from the Oval Office on the Gulf of Mexico oil spill makes it clear that Obama’s sweet voice no longer suffices, not even for his biggest boosters.

The thrill that Obamian rhetoric once sent up the leg of MSNBC commentator Chris Matthews is apparently gone. Obama’s repeated references to Energy Secretary Steven Chu’s Nobel Prize, Matthews said, now make him want to “barf.” He compared Obama with former President Carter. Host Keith Olbermann, who normally wouldn’t hesitate to lavish praise on Obama for coughing, was almost as blunt. “It was a great speech if you were on another planet for the last 57 days,” he said. Even Howard Fineman, a font of Washington conventional wisdom and a huge fan of the president, suggested that Obama wasn’t acting like a commander in chief.
