This race is still a Tossup. However, Bredesen maintains a small edge as of now.
I don't get the Ted Strickland comparisons. The assumption is that Strickland got blown-out because he was a former governor? No, it was because his campaign was a joke. Bredesen can easily win if he doesn't make the same mistake.
For the record, I wanted comparable numbers to prove Bredesen is different. Sure enough, Strickland was at -6% approval in May of 2016.
I know we are not in July yet, but in July 2016, Evan Bayh was leading in Indiana by 20 percentage points so if Bredesen is leading by 3 percentage points now Blackburn has a quite decent chance to defeat Bredesen in November.

Bear in mind that this was before Bayh’s forgetting his address in IN lol
Bredesen probably won’t be in the same boat, and doesn’t have obvious or traditional lines of attack against him.
