Because I believe in a viable two-party system. Right now, the Republicans defecate in their trousers for fear of the ueber-right-wing TEA Party/Evangelical element. Lincoln and Teddy Roosevelt have to be shaking their heads at the marginal positions on too many issues that the fringe mandates be the litmus test. Yes, I voted for the incumbent because I didn't want corporate elitists like the Koch Brothers imposing their neo-Gilded Age view upon the rest of us. A viable Republican Party is necessary to keep the Democrats honest and pull them back from their left-wing fringe.
