Coming back to Alabama?
Short of a medical issue, or the proverbial "dead woman/live boy in his bed" situation, Tubs will be the next governor. He's a reliable conservative, and although the auburn connection is distasteful, he's probably as well equipped or better to run the state as other recent governors.
As I've mentioned, usually governors become senators, not the other way around. I'm hopeful Katie Britt stays in the Senate and builds seniority to help the state from where she is. About a week ago, the New York Times did a feature article on Britt as a rational broker to Trump, probably the most positive article I've seen from them on a sitting republican.
