I'm not a big fan of Mitt Romney as my President. I doubt seriously his dedication to actually shrinking government rather than slowing the rate of expansion and he has shown no desire to scrap the labyrinthine tax code in favor of a flat tax. Who knows to what extent he'll actually deregulate business, lower taxes, drill for oil everywhere, or rid us of the useless departments of Education, Commerce, Energy, and seriously reign in the EPA. Essentially, I think as President, he'll be George Bush v2.0.
That said, Newt Gingrich and Rick Perry are attacking Romney for participating in the capitalist process as if venture capitalization and free-market creative destruction were immoral. For their phony, populist attacks on the free-market process, not just that Romney was involved, I cannot vote for either.
Being libertarian, I cannot vote for self-styled choirboy Santorum either. That leaves me with a choice between Romney and Ron Paul. Ron Paul may still get my vote in Alabama's primary, but we'll see. The question for me is electability. Can Ron Paul appeal to enough social conservatives to beat Obama....I think not.
