It's always the lesser of two evils. The lesser implies there is a greater evil. O will continue to destroy the economy, so that makes him the greater evil in this case. At this point, it's going to be O or Mitt. To vote for someone else or not vote is a waste and a "vote" for O. One of the two will the elected. The greater evil is worse than the lesser so that means the lesser is better. Mitt is not my first choice, but I plan to voter him the lesser=better.
