#1 - He was already known to be a moderate and did not inspire the base conservatives.
#2 - He is a Mormon. Personally I don't care what religon a politician practices as long as they have integrity BUT there were a large number of "Christians" that couldn't bring themselves to vote for him.
#3 - He could not carry the population centers. The states that carry the large number of electoral votes will vote Democrat every time UNLESS the another candidate can convince them otherwise. Romney could not do that.
Chicago style politics —you can’t win if the election is close. It has to be a blow-out or they will find a way to “win.” I think they knew they had it in the bag for awhile. Why would a president show up for a debate completely unprepared if he thought he was in the fight of his life? Why would a vice-president do his best Nicholson Joker impression if he thought he was in danger of losing an election? It all seems suspicious now.....
