For some time now, I've been trying to figure out what would motivate a Republican to cross party lines and vote for Hillary even if he thought that Hillary would have a better chance of beating McCain than Obama.

I have tended to assume that hatred of McCain or wanting the GOP to lose would be the only possible reasons, but it finally dawned on me that there might be an additional reason.

There may be Republicans who don't mind having McCain lose to Hillary if that were the price that had to be paid for preventing the possibility of an Obama presidency. Thus, this group may be voting for Hillary for entirely different reasons than commonly believed -- i.e., not to save the Republican party from defeat, but to save America from Obama.

While this might be a form of strategy, is it reasonable to call it a Republican strategy?

Does anyone know of any crossover voters thinking this way? I don't think I'm just imagining them as there's this bumpersticker:

Wherever they are and whoever they may be, if Obama's the nominee at least McCain won't have to worry about them sitting it out.

It has to be remembered, though, that in politics, nothing is permanent. Rick Santorum, for example, was long known as an "Anyone But McCain" man. Until yesterday, that is. Now he's explaining "Why conservatives should support McCain."

Why? Because McCain is not only Anyone But Obama, he's also Anyone But Hillary!
