Even Obama seems to have lost his cool in the latest round of debt talks. Republicans said Wednesday’s meeting got so tense that Obama stormed out the room, although the White House denies that account. House Majority Leader Eric Cantor said the president warned him not to "call my bluff," and Obama said there had been too much "positioning, posturing and catering." The officials said Obama ended his statement, stood up, and then headed back to his office."I know why he lost his temper," Cantor said. "He's frustrated. We're all frustrated."
