Due, I think, to the fact that the Demos controlled Congress for 50 years or so, the GOP got used to making deals to get things done. The Demos never did learn it. As a result, the GOP has missed a lot of opportunities to really mess up the Demos - and I'm afraid this is one of them. The older GOP members are too afraid that if they try to mess up the Demos on anything that it will come back to haunt them later. So even with the GOP in charge of a house of Congress (or even both houses) the older GOP who are in charge won't push the Demos on anything.
