The problem is Tuberville is not a strong Trumper. His campaign manager has said some nasty things about Trump.
“....Tuberville is not a strong Trumper”
Maybe a few unknowns, but much better than either Sessions or our other two senators from Alabama. His platform at the link:

Tuberville: If I was in U.S. Senate today, I would be calling for a full and thorough investigation into the now-disproved Russian collusion probe of the 2016 elections. I believe that this witch-hunt was a political stunt to try and call into question President Trump’s legitimacy. I will stand with President Trump and fight any attempt to discredit his Presidency.
Much more than we could ever expect from Sessions!
