The Republicans are already lined up to back him, they know going with McCain or Rudy Giuliani is the only way to win...i mean who else would they back? Bill "a taller version of Al Gore with an MD" Frist? Rick "Crazyman" Santorum?
As for accomplishments and cowardice, maybe more would get done if the parties stopped B**ching and learned to compromise...look at the things McCain and Obama are trying to do...they just get blocked. As for "nothing" what do you call the biggest overhaul in campiagn finance law in 3o years?? I'd call it something.
As for making nice wiht Bush after 2000...well you can't expect to win ANY office if oyu burn all your bridges, campaigns are bloodsport, but when it's over and done you need to be man enough to get along with the guy/gal that beat you.
