Likely R -> Titanium D
In all seriousness, I hope people will drop the Bayh comparisons. If Bredesen were to tank to a double digit loss, I don't think we'd be seeing anything better for him than a 5-6 point deficit in the polls by now, since he's had plenty of time to lose popularity and be seen as a generic D. My gut still says Blackburn pulls out a narrow win, but no one should be calling this race a forgone conclusion right now.
Yeah, even if Bredesen ends up losing, he's probably not going to lose as badly as Bayh.
