Yes, really. By the time the election rolled around, I could:
vote for Obama
Vote for Romney
Realistically, those were the only choices. Inasmuch as I want the ACA to go forward, Obama was actually the only choice, as Romney wasn't saying anything at all I could get behind.
Any idea of voting for Paul or someone even less popular would have lost Obama a vote against Romney, while doing absolutely nothing to see the person I voted for actually get elected. I could not, in good conscience, do *anything* that would, or even might, help Romney.
Given the circumstances, I am content with that vote; I think it was the best choice available at the time.
If you think you can fix the American political system, by all means, do so. Until then, though, it's turd sandwich or shit bagel. Picking is a matter of holding one's nose and hoping you really like bread.
