There are critical differences between the two choices, many of them stark. Should Romney win and with the help of Congress trash the beginnings of a real national health plan it will be several decades or more before you'd ever see anything even remotely like it come up again. Insurance rates would rise drastically, and just about any payout would be forfeit for some 'pre-existing condition.' Coverage for transition, sure if you're a hot-shot executive with a gold plated policy, for regular people, never. The war in Afghanistan would be ramped up, new wars in Syria, Iran and perhaps even confrontations with Russia would come on-line - the monetary outlay would gut most domestic federal programs. Gay and transgender issues would not even receive a hearing, much less any action. Voting would become harder for a lot of people. Unregulated business and corporate power would grow, and in combination with enhanced states rights would prove to be very bad for the poorer states, and what's funny (in it's own way) is those are going to be the states that vote for Romney. Really, if you put it to a popular referendum (particularly in the bitterness that would follow such an election) would New York or California vote to send money to Mississippi, or Dakota? Nope, they would be on their own. Hell many parts of the US are damn close to being Third World as it it, but this would complete it. But just think how much more cheep plastic stuff you could get at WallMart when the people in Mississippi would get to work for lower wages then China. So the poor would get radically poorer even faster, while the rich would do very, very well. Perhaps they might Tinkle Down on some on you.
And, mostly, once the few people like Sheldon Adelson and the Koch Brothers buy the country cheep the cost to get it back would be most dear, if it could be done at all. It is slightly humorous to note thought that the first causality of the Citizens United decision was the the Republican Party itself.
Luckily they are running the most incomplete campaigns I've ever seen and it's fast slipping out of their grasp. Hope that in their idiocy of trying ban contraceptives from women, trying to make some forms of rape OK, race-bating, attacking the Hispanic community, and the legions of stuff that's even sillier, that they are going to kill the down ticket races too.
