I don't question the fact you're not a Republican - I'm not either (though I do support a majority of their candidates). I think many people would simply ask, 'why claim party affiliation at all'? I can understand why my grandfather stubbornly claimed to be a Democrat to the day he died - but he was never one to foster debate and discussion over the issue.

Believe me, I ask myself that question frequently.
As counterintuitive and paradoxical as it might be, I do think that the Democratic party at this point in time actually offers conservatives a better opportunity to move forward with a conservative moral and political agenda than the GOP does.
In the longer term, I think that partisan politics as we know it is on the way out and will be less of an influence than it is today. Not much to do with politics per se, but economics and technology.
