This election is going to be very close. Individual votes will not be symbolic, they could very well determine a winner.
I understand your frustration, but this is no time to be pissy. If everyone who is disgusted with politics stays home, it'll be the people who actually ENJOY this kind of circle jerk who will get to decide our future. So man up, grit your teeth, and vote, dammit.
If you wimp out, I swear I don't want to hear a single goddamn complaint out of you for the next four years. You got it?
