Won't happen. Politicians act like X because they think X is popular. If the GOP gaines both houses by supporting socialism, they'll still believe (even more so) that socialism = votes. So ... why would they change?
What you see is what you'll get.
Vote Libertarian. The LP will eliminate socialism, so that only those who truly want to work will come to the US.
Most great civilizations have collapsed because the "leaders" gave away the wealth of the country just to keep the peasants happy (or in line). The people became lazy and the money became worthless...the next thing was opression and dictatorship. I don't think it will be long until warlords will be patrolling neighborhoods in old beat up jeeps with a worn out 50 cal. attached.
