I only believe the Bredesen win in TN when I see it ...
A lot has changed in TN recently and the state got much more Republican + many voters might not remember Bredesen as the popular Governor he was.
Plus, TN has always been a major letdown when it mattered: In 2000, it was Al Gore's homestate and he didn't win it, enabling the catastrophic presidency of GWB.
And in 2006, when it looked as if Harold Ford was about to win it - voters got scared by the racist "Harold, call me !" ad and voted for Corker.
So, I won't be too optimistic about Bredesen in the next months.
There is gonna be a rally around the flag, in terms of GOP, as 9/11 gets closer and states like TN, MS, and TX will turn more GOP leaning.
I don't think the anniversary of 9/11 has a lot of bearing on election results...
