Well, Guiliani certainly ain't the ticket for that. Fred Thompson sounds more like someone who fits the bill -- conservative, but not an ideologue, charismatic, well-liked, consistent, honest, and a track record of winning big using unconventional methods.
There's going to be some real disappointed conservatives if Thompson doesn't run. People will I suppose turn back to Hunter as the great Conservative hope. I was worried when the stories of Thompson's cancer came out. I really don't know Thompson so much (beyond movie appearances). I hope he's articulate and I'm assuming his acting roles have made him media savvy. We've really taken a beating in that area.
