This year voters don't see much choice to improve their lives for the next four year term. President Obama subscribes to the philosophy of The Minimum Acceptable, a caretaker of the political status quo and hand-holding a petulant Big Business.
Gov. Romney is viewed as the guy who will finish off what's left of the middle class, taking away Social Security and getting rid of what affordable health care exists from Obama's minimal and very expensive legislation. And, oh, yeah, Romney and his conservatives don't "believe" in the minimum wage; in fact, they want to completely abolish it.
Neither candidate is telling the voter what to expect the next four years on the economy, foreign policy, health care, equal pay in the private sector for women. Romney thinks women live in binders like some abstract thought. (That's the polite version.) Obama passed the Lilly Ledbetter Actto help women in the public sector but stopped short for helping women in the private sector. It's that stopping short Obama is so famous for doing that ticks off the voters, especially the undecided.
