re: If the libertarian eye doctor doesn't run, which R would you support?

If we're talking primaries, Carson. If we're talking general election, whichever R makes the ticket. I vote ideologically in primaries, but I vote anti-Proggie in the general. I'd love a libertarian president, but you can't turn a ship this big, this fast. It'll take incremental turns to get the US down a libertarian path, and while that's the way I want it to go, the unfortunate truth is that it would likely take decades to undue what has been done by both parties.
