If I'm a Republican, and I have a Republican congressman, I like him because he represents my views, for the most part. I dislike Congress as a whole because half of it disagrees with my views, and the half that does agree with them is hamstrung by the half that does not.

Despite the rhetoric of "both parties are the same" people really only care about a few issues, which the parties differ on: taxes, welfare, religion, education, social issues, etc. I just got hassled on the street today by a college-aged male to support planned parenthood. Who do you think he votes for? Why? What does he think of Congress?
