As far as Tennessee goes, the Democrats may not nominate Harold Ford Jr, but what about Reps. Jim Cooper or Lincoln Davis? I imagine one of them could give us some trouble.
The last time they nominated Cooper in '94, he went down in flames, though I'm sure he'd like to be a Senator (which his much-more Conservative daddy (Gov. Prentice Cooper) was denied by Gore, Sr. back in 1958), but I still think he's a tad too liberal. Lincoln Davis might be a good choice for them, but he may be too Conservative for the nomination. His reelection campaign made you believe he was a Conservative Republican. The question is whether or not all 3 (Ford, Cooper & Davis) decide to jump into the fray and bloody each other for the nomination. At this point, it is ours to lose.
