That is the last president who lost re-election in a head to head matchup with no 3rd party candidate and no primary challenge. That happened 80 years ago, in 1932 and shows just how hard it is to beat an incumbent president running for re-election who faced no other challengers.
As usual, Ann Coulter is right on target. Don't blow it in the mid term elections! They will be a golden opportunity just like in 2006 for Democrats.
