L.A. TIMES: Why Obama’s sudden news conference today? And what he’ll say. “Here’s the scary thing for the new White House: the terrifying words ‘Jimmy Carter’ have started appearing in print and on the air . . . . Sen. John McCain’s angry Senate Neda speech Monday, also reported and analyzed here with a video, dramatically changed that equation, forcing Obama to talk today more powerfully about the power of talk. . . .Obama needs to re-seize the initiative; hence, Monday’s decision to schedule a Tuesday presidential news conference. Such staged affairs are not only irresistible to the media (CBS will break into normal programming to carry it live), but they suck the oxygen out of any other competing story for the cycle.”
