Taking money from the Romney men, and therefore being in thrall to Romney and his adherents & their agenda is a peripheral issue? You might want to sell that fish somewhere else.
If he does turn Left (I doubt he will), fine, look elsewhere. Unlike some around here, I'm not in love with any particular politician (Sarah comes close though), I'm in love with freedom. Our focus should be on our common #1 enemy, big government, and we should unite around that cause and find those who are most faithful to it.
Those who don't are part of the problem IMO.
