Still, if it's not him, then who?

Frankly I don't see anyone in the current Republican field becoming US president. Guliani and McCain have a long shot, because people somehow "like" them. But Guliani actually botches up quite a lot on the campaign trail, and McCain is a bit too old by now. Still, if Fred Thompson gets the nomination, the Dems should be lucky.

You never know what happens, of course. But this is a very weak field of contenders for the Republican nomination, facing an already fairly strong field of Democrats.
