I wonder if the GOP can come together as one, even if they were able to win majorities in both houses of congress. The Republican Party seems split on incompatible ideological lines and I foresee a power struggle among some very ambitious personalities in both the House and Senate.
If the they were to win, however, I suspect we would see little pragmatic governance until it became obvious they were going to lose big in 2016.
We would likely see further efforts to cut taxes, reduce abortions, attack unions and reduce the size of government by cutting budgets, resulting in massive government employee layoffs.
We would see more efforts to privatize government services, less regulation in terms of environmental protections and privacy (keep in mind the government's ability to collect information on you is limited by law and overseen by the congress, no such requirement keeps the private sector out of your bedroom or bank account).
We would see serous efforts to undermine or eliminate Social Security and to dismantle Medicare/Medicaid and Obamacare, with the insurance and hospital lobby writing new laws and imposing new restrictions on access.
Those of you who 'hate' Obama and Democrats ought to take off your dunce caps and begin to really think about what it takes to oversee a nation as large as ours, in a world as unstable as ours.
