Barack Obama admitted Thursday he deserved to be "slapped around" over the chaotic debut of his health care law, and pledged to work hard to restore confidence in his reeling presidency. Obama, with his approval rating tanking and fellow Democrats in open revolt, promised to fix website and coverage failures that have hampered the rollout of the new law and sparked an opening for gleeful Republicans. "These are two fumbles on ... a big game, but the game's not over," Obama said, announcing a plan to make good on his discredited promise that Americans who liked their existing health care plans could keep them. "Had I been informed, I wouldn't be going out saying, 'Boy, this is going to be great,'" Obama said, though he warned that buying health care was a complicated business and was "never going to be like buying a song on iTunes."
