Give people two options, neither of which they find appealing, convince them that a third option, a genuinely attractive one, is just not practicable and that they must thus choose between the bad and the worse, and you’ll be able to get them to choose something they would never otherwise choose.

You can get people to do anything that way. You start by offering them a choice between something that is just marginally unpleasant and something that is really repellent. Once you’ve gotten them to choose the marginally unpleasant, you raise the bar (just a little mind you, you don’t want them to catch on to what you’re doing). Now you offer them a choice between something to which they have really strong objections and something that is deeply offensive. Most people, of course, will choose the former, if they think it’s either that or the latter. Now you offer people who’ve become inured to living under objectionable conditions a choice between even worse conditions and something that is truly unthinkable. It’s not mystery what they will choose.

There’s been a lot of angry posturing from Americans who think of themselves as progressive about how the purported political center in this country has been moving inexorably to the right, yet it’s these very people who are directly responsible for the shift. If you vote for a candidate whose farther right than you would prefer, well, then you’re shifting the political “center” to the right. Republicans aren’t responsible for the increasingly conservative face of the democratic party. Democrats are responsible for it. Democrats keep racing to the polls like lemmings being chased by the boogeyman.
