Fundamentally, legislators view their job as adversarial, not collegial. This is completely contrary to the assumptions made by the founding fathers about enlightened self-interest and collective wisdom. Personally, I blame the adversarial quality of news broadcasting as one cause, but causes aren't really the point at the moment.
Both sides are savagely defending positions, not pursuing common interests and the collective goal of protecting the nation. If they could read, our legislators would profit from basic negotiation texts like Getting Past No and Getting to Yes.\
Good negotiation requires finding a win-win solution, which is the opposite of adversarial.
At this point I am so angry with these children that I want to swat their collective behinds.
Like the President, I could live with anything EXCEPT doing this all again in six to nine months. I would prefer to see soak-the-rich taxation added into the mix.
What I cannot see is continued tantrums, sulks, and "you can't make me' from the infants we seem to have made our representatives. Yecch.
