It is a beauty pageant and the best outcome they can hope for is that the least ugly girl wins.
To be frank, they both suck epically.
Obama had his shot when he first came to office when he had a democratic congress, he could have really made a difference (good or bad) and he blew it by focusing on the wrong things, right now he is a lame duck. Obama Care is about the worst universal health care scheme I have ever looked at, that is his legacy and great achievement. He is a smooth talker and looks presidential but his record is mediocre at best. He was supposed to be a great hope and he fizzled.
Romney, well his taxation policies prove one thing, he cannot add or subtract. Simple as that.
Obama is likely the least ugly girl, but very far from a good choice (and there is no good choice).
