I think the GOP would become more moderate, and possibly have McCain run against Gore in the 2004 election.
I don't think so, but my dream scenario would be the GOP sweeping in 02, 04, and 06, topping it all off with Liddy Dole / Rudy Giuliani in 08 or even 04. I think the GOP would take a middle-of-the-road, "no continuity" approach, I.e. no old farts who have run 4 times before and lost all 4, no family of past presidents, etc. As anti-establishment as possible. Which leads us to a potential George Allen victory, provided he keeps the "makacas" to a minimum.
