If a Bayh or Warner have a chance of winning in 2008, they will decimate any of the mentionable Republican except for Giuliani and McCain.
Giuliani and McCain are not mere politicians, they are celebrity superstars- a huge plus in these United States- and they will beat anyone.
If either one of these guys gets the GOP nomination in 2008, watch how quickly they go from "moderate" to "fascist" in the eyes of the media. By the time November of 2008 rolls around, they'd be so thoroughly re-cast by the media that we'll be sitting around here on FR wondering what the hell the GOP was thinking when they nominated such a miserable candidate.
