I disagree with your forecast of a Dem seat gain in TN. Marsha is going to win that race.
Let’s root for Blackburn but TN has had long-term sentimental attachment to the Democratic Party.
I really hope you are right. Bredesen is popular and VERY well funded. It’s going to be tough.
If nothing else, Blackburn should become a beneficiary of the general trend. Likewise Arizona should be safe. As some of the commenters here would suggest, I think the article understated the case. Ill go +4 for my prediction at this point.
