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.

The American worker has been lied to for decades. Election year after election year, politicians pronounce the American worker the best in the world, as if this was meaningful. Rarely does a politician speak the truth: for decades now, American workers have been thrown to the wolves.

There are some new gangs in our political neighborhoods called "super PACS" and they distorted the outcome in a number of states during the Republican presidential nomination campaign.

While they may have a point about the magnitude of cash flowing into negative ads this time around, and while they may indeed have a point about the insidiousness of corporate money in American political campaigns, the nastiness itself is really nothing new.
