I agree about Sessions having some role in upcoming trials. It doesn’t seem likely to me that he’s going to win his runoff with Tuberville in July, especially with POTUS slamming him so hard - which begs the question. If Sessions understands his role, then why is he running in the first place? If Trump wants him to lose, then what purpose does it serve to run and get beat? Eventually it will make sense.
I have thought for a long time that Sesssions isn’t mean to win the Senate but has another important role to play. By running, he’s making his character and position clear (white hat to the max) and also not getting his feathers ruffled by Trump’s goads. Seems that whatever role he will play is more important than the Senate seat.
