Obama wins the November election. Republicans strengthen their positions in the House and Senate setting up gridlock. The media has two years to blame Republicans for everything down to toenail fungus.

Obama has the final two years of his lame duck presidency to completely destroy what is left of America.
Check...and mate.
Your scenario is terrifying and well within the range of probable outcomes.....
