It was also a similar situation.
No. If you were alive back then and watched TV and read the papers you would realize we were intensely fighting two wars and Americans are loathed to change horses in the middle of a war. Iraq is over and Afghanistan is winding down with date certain for an exit. Romney for all his stupid bellicosity when pressed says he 100% agrees with the president's time table. Actually the war wasn't even mentioned this election.
Also expand out and look at the legislative branch. There were tons of Dem upsets and the Dems added more seats to both chambers.
