I toyed with it, but haven't made the move yet. I'm more conservative than anything, but have always been a registered pubbie. I feel kind of like Senator Zell Miller in respect to the party that I knew leaving me.
There's no political equivalent to the idea of Purgatory; no reasonable foundation for a vote to "go through Hell to get to Heaven".
That's NOT saying that a vote to move in a positive direction will not have painful implications; as bad as things are, they cannot be fixed without sometimes considerable pain. Ask anyone who's been a patient in a hospital burn unit. What I AM saying is that a positive change is not reasonably achieved by voting to move in a negative direction.
In that regard, the RNC has left the rails.
As I state on my Profile page, with the RNC matching the leftward march of the DNC step-for-step, I'm not leaving them; they're leaving me. They're decreasingly reliable as purveyors of solutions because they're increasingly populated by individuals who are carriers of the very political ailments that drag us leftward. Bluntly, "Republican" is, now more than ever, tantamount to "Moderate"; the most bland and undesirable of all possible political persuasions owing to its very LACK of any actual persuasion.
FWIW: here's the biblical commentary on being a moderate:
15 'I know your deeds, that you are neither cold nor hot; I wish that you were cold or hot.
16 'So because you are lukewarm, and neither hot nor cold, I will spit you out of My mouth.
Revelation 3:15 & 16 NASB
