Chaffee might not be so lost as you may think, now that he's facing a demonstrably more conservative challenger in the next election.
I'd love to think that is true, but Chaffee's record is one of unabashed liberalism. Most of the "scorecards" have him much more closely aligned as a Demodog than is the case for any other RINO in the Senate. I haven't noticed that his voting has become suddenly more conservative this year in any of the voting that has taken place.
Sorry. Chaffee must be considered one who must be forgotten - just about as important as Jumpin'Jim.
