Because Congress is less popular than Communism:

There is a deeper message, which is that John Boehner and Mitch McConnell has managed to take an institution which already held in low esteem, and absolutely trash it.

While the “very serious people” in the Democratic Party think that this is a political advantage, they are wrong.

You see, the foundation of conservative electioneering is the idea that government does not work, and as much as they might damage themselves in the short term, they are, in the long term, undermining the very idea that government can regulate the banksters, keep the poor from starving, protect us in the work place, and provide healthcare for the rest of us.

While someone like John Boehner may be too gin soaked and stupid to consciously understand this, he, and His Evil Minions^™, do understand that constant gridlock and dysfunction plays to their strengths, and that it’s a lot easier than doing something constructive.
