Romney at one time was a successful governor of a blue state. He worked with a Democratic majority in the state legislature, until they got all partisan on him near election time. He did a great job running the Olympics. He got his law degree from the same place as Obama, without affirmative action helping him.
The vast wealth he has he earned himself, though he did get a good start from his dad, but his dad came to the US as a child with next to nothing, and Mitt had three siblings to share that with. Obama did not have that object lesson, for all practical purposes an only child, his father being from a wealthy and well-connected family and his mother of upper middle class parents.
I don't think Obama stands a chance against what is sure to be an even more Republican Congress. And he hasn't been a strong enough advocate of women's rights or LGBT rights to make a difference on those issues.
All things considered, I would rather have the slimeball who says what he stands for than the one who lies about it.
