Polling was good, but the cheating was extensive and the election manipulated:
1) Debate moderators (Candy Crowley) giving clear advantage to BHO.
2) IRS intimidating conservative groups.
3) Media totally in the tank as usual.
4) Heavily Democrat urban precincts casting more ballots than the number of registered voters in the precinct.
A lot of hanky panky to say the least.
Missing from your list:
5) Really crappy pretend Republican as our nominee who supported both Abortion and the Gay Agenda.
