The problem is that Obama has already shown himself to be the hands down, worst president I have ever voted for.And how many would that be? If you're, say, fifty, then the possible presidents would be Carter, Reagan, Bush 41, Clinton, Cheney and Obama. I'm going to assume that only half of these are in the "voted for" pool, and observe that there is in that case no shame in placing third behind Messrs. Carter and Clinton. It seems to me, hnick, that you needn't vote for Obama twice. If you do not wish to see Romney/Ryan enthroned (and I assure you that they would move energetically to put to rest your amusing conceit about the near-indistinguishability of Obama and the GOP), your personal contribution needs only to extend to voting for the alternative choice you think likeliest to block the Mormchurian Candidate's accession. If you sincerely believe that this would be a write-in for, say, Ralph Nader or Ron Paul, you will find no one here who will second-guess your ethical stance, although a number of us might be found to question your mental competence. If you believe that the plausible alternative is Obama, you may exercise your franchise in his direction while averring, should the accusing gaze of posterity ever fall upon you, that you were voting against Vulture and Voucher in a gesture of realistic revulsion signifying in no wise approval of the guy you voted for in 2008 who thereafter turned a deaf ear to your repeated entreaties for a pony.
I, too, would like a Chief Executive considerably to the left in most particulars of the one we have, but as the powers are aligned in our faltering global empire and in the brutal senescence of late-stage capitalism, that doesn't appear to be in prospect. Experience persuades me that the lesser of two evils differs from the greater by being, well, less evil, and that this is, while well short of the best of all possible worlds, meaningfully preferable to more evil. Only if you imagine that the country will embrace our sensibilities once it's had a taste of the Tealiban regnant could you passively countenance their triumph, and I'm here to tell you that I sat through the original version of that movie in 1968, and that Nixon's election didn't bring the revolution a damned day closer.
A shout-out here to Another Scott, who has been making this case more patiently and coherently than I can contrive.
cordially,
