This presidential campaign is shaping up as one of the most personally nasty in modern times -- and more quickly than experts thought it would. Mitt Romney and President Barack Obama already are in choreographed hand-to-hand combat mode. The GOP's presumptive nominee has angrily demanded an apology from Obama himself for a campaign staffer's suggestions that Romney may have committed a felony by misstating his role at Bain Capital in a SEC filing. Romney called the remarks "outrageous" and "beneath the dignity" of Obama and the presidency. Not only did the president not apologize, he all but scoffed at his foe. Obama did not pawn off the controversy onto his campaign staff or position himself above the fray as a sitting president with much more lofty work to do.
