Oh, no. I'm aware there are tons of other choices -- Libertarian, Green, Constitution Party -- but the only ones who make the laws are either Republican or democrat (with the occasional Independant tossed in).
So if I want to have any voice at all, even a small one, I have to choose between Rs and Ds. If that turns out to be a choice between the lesser of two evils, I prefer an evil R to and evil D. Evils Rs only take some of my money. Evil Ds want it all.
It's amazing what some people will sign onto for the false perception that they have a say.
