As a Tennessee voter, some of the races, especially in the primaries, I’m not overly excited about. Some I have mixed feelings about. But this one is clearcut. Blackburn is a good candidate. She is the main reason that I’m looking forward to voting this election cycle.
Bredesen is popular in the state. If he is able to attract enough moderate/establishment Republicans, it could end up being much, much closer than this poll indicates. But I think that Marsha will win...hopefully.
You are sort of where I am, and I too am a Tennessean. Marsha is not particularly well-known statewide, and she is a very willing Trump proxy. So if Trump’s popularity were to decline among suburban GOP moderates, that could make it much closer than this. Still, the inherent advantage of being a Republican in Tennessee is likely enough to get her to the Senate.
