No.
Alan Keyes, for all his bluster, is a blowhard that's never been elected to anything. If he is so serious about getting into politics, perhaps he should run for Congress before another Presidential attempt. At least that would diffuse the charge that he runs to promote his radio show, and now TV show. Don't get me wrong, I like Keyes, but he has a tendency to be grating.
Pat Buchanan is NOT a conservative. He used to be, but now Populist is a better description. If you still doubt this, read the transcript of his "culture war" speech at the 1992 Republican convention, and contrast that against his positions today. If you still think this is the same guy, I'll have some of whatever you're smoking.
Finally, I firmly believe that most of the "I'll never vote for Bush again" crowd here on FR didn't vote for him in the first place. The man has done exactly what he said he would do, and has exceeded expectations for many of us. Of course, this will earn me the tag of "Bushie", or "Bush-bot", or whatever epithet is being thrown around by the line-in-the-sand crowd today.
I have now donned my asbestos suit.
