You can’t hold congressmen (who represent DISTRICTS) responsible for how entire states vote. Geesh.
While you are technically correct, people look at congress and see Republicans, Democrats and Washington. What someone did for their district no one except that district cares. Its what they did for the nation that everyone sees and judges. That aside, how effective has Boehner been resisting Democrats when he had some healthy numbers? How the hell will be more effective now?
