At least I don't expect Romney to win in November That'd be awful.
Indeed. Our current president is a Nobel Laureate. A Nobel Peace Prize winner, nonetheless, who was awarded that coveted prize even as he was the commander-in-chief of a nation engaged in two wars. Why change horses now? We would much rather have another four years of high unemployment, taxpayer-funded bank bailouts, billion-dollar stimulus packages, cash-for-clunkers deals, Presidential missions to the International Olympic Committee that do little more than embarrass the people of Chicago, and Beer Summits in the Rose Garden featuring privileged, self-righteous academics and Cops Who Act Stupidly.
You stuck in 2009?
Anyway, the answer is quite simple, because the alternative is Satan.

Not that I think bank bailouts or billion-dollar (too small!) stimulus packages are inherently bad things. The idea that a President Romney would do anything to lower the unemployment rate is laughable, and the other two examples you cite are irrelevant minutiae.
