The voters will decide what the real question is, not you. And a great deal will depend on how the other candidates come across. If none stand out in the crowd in a positive way, Sessions might well win if he decides to run.
I would think that Trump would have something to say about this. If Trump puts up with weasels like this, that disturbing for two reasons. In the first place, it could mean that Trump is compromised and needs to show his fealty to globalist scum by letting Jeffie run for his old seat. The other less likely reason could be that Trump is clement which doesn’t seem consistent with his personality.
Trump doesn’t need this squirt pissing on his shoes. Trump can support someone better.
