How does a white man vote Democrat?

Just reading through Modo, the Dodo, and she says something that she thinks is really cool, but ain't.

When a few old rich white men are the only ones who succeed, that’s not just unfair, it’s untenable.

You know, it isn't that I think that "old white men" are the only  who succeed, but if they are, that's not why they succeed.

It's so wrong, it says so much about Democrats.  If you are a rich, old, white man, you are scum, I suppose.

How can any white man ( barring the homosexuals ) ever even consider voting Democrat?  It's like spitting in your own face.
