If Rudy is the nominee, there will be some few people who will say "I'm staying home" or "I'm going third party." I will be all over those people like stink on a wet dog, They're suckers, and they shouldn't be anywhere near a voting booth.
However, at this point, every conservative should be trying to get a conservative candidate in the White House, and you're right, those of us who are doing so are mocked for it. It's bizarre.
It is my vote, and I will cast it where I damned well please. The Republican Party would do well to remember that I am only one of a multitude who feel that way.
The suckers I see are the ones being buffaloed into accepting a rip-snorting liberal for a candidate as the "only one who can beat" another rip-snorting liberal.
Not much to gain by that, but if all the urbanoconservatives think that is a winner, so be it. At least you can wash the stink off a wet dog.
