Not really they can be replaced if the GOP hiarchy would permit as much that is the source of the GOP unwillingness to deal with it's own corruption or RINO's. Tennessee has several good conservative congressman more deserving to be senators.
One would easilly win due to name recognition and good reputation. That one is Rep. Jimmy Duncan. Another is possibly replacing our RINO governor. That one is Van Hilleary. A third has great experience on DOD issues which is Zack Wamp. I think any one of these three could unseat Fred and Bill. I also think they would get plenty of cross over votes as well.
I'll vote for a good GOP canidate. I voted for Wamp this time. Unfortunately when it came to U.S. Senator this time I did not vote as both choices were pathetic.
