@farmerman,
While I think Romney ran a decent campaign, I think he made three whopper errors.
1) Opposing the car bailout: This was a big risk in Ohio and Michigan and he paid for it. Obama's handling of the auto bailout was one of the highlights of his first four years both in effectiveness and in popularity.
2) Getting caught in the Jeep lie. Same thing here although perhaps Ohio was lost and it was a hail Mary pass. Having two extremely important employers publicly call you a liar is not the way to carry a swing state.
3) 47%. Even conservative pundits where shocked by this one. If there was a moment that cemented the view that Romney was Thurson Howell the 4th it was his callous disregard for the working poor and the elderly.
