no national money is going into any of those districts
everyone rates them safe for 2010. it will be tough on the GOP candidate if they cannot get on any targeted list.
No, but Davis and Gordon are very defeatable if a first-tier challenger stepped forward. Davis never faced one and Gordon last had a close shave in ‘94 & ‘96 (before that, he faced a younger Marsha Blackburn, who was a promising, but unknown candidate at the time). Gordon had Williamson County excised for 2002, because that county alone had enough power to vote him out, because there are almost no Dems elected there (and that gave Blackburn her opportunity to take a run when they stuck it in the 7th).
In 2012 if the GOP controls redistricting Davis, Gordon and Tanner will find their districts more Republican.
