Well my first thought, is that one has harsh features, and the other is easy to look at.
I have never liked either of the Obamas, one is a fucking liar, and the other has a smile similar to that of a demon that eats children. Some people are afflicted with smiles that represent evil incarnate. I have learned to recognize those creatures.
That said, I have a fuck of a time understanding how one could find any democrat attractive.
