Political differences?

Please tell me your political affiliation and why you disagree with people of the opposing party. I'm trying to understand the true divisions in this country. I'm going to try to answer each of these. I want real political differences not, "They support ______." I don't care who you support. I want the real reasons you disagree. Maybe if we expose these minor differences to the light of day, we'll realize we are all working for the same goal.
