Right wingers should blame McCain & Palin for their epic defeat (McCain for picking her; Palin for coming across as an airhead to such a degree that she stereotyped herself and actually scared Americans into not wanting her anywhere near the commander-in-chief role).
They lost the Executive Branch, the Senate & will lose the Supreme Court (de facto, not de jure) within the next 8 years.
Now that's an epic defeat.
Mitt Romney may have helped stem the losses in the Senate.
Palin was the biggest strategic mistake of a pick in a long, long time, by either party.
