I don't expect either will happen. I may be proven wrong but I continue to think the allegations are not credible. There is an concerted effort to establish a pattern of behavior. I guess it would be construed as opposition research in some circles.
I think Moore will stay in the race and there will be scrutiny of the stories of the women involved. The stories may fall apart. We will see.
I am not sure of all the electoral gyrations. I expect Jones would march in lockstep with the other Democrats if he wins the election.
I read somewhere if Moore withdraws and wins the election may not be valid and another election would be necessary. I have no idea if that is the case.
I expect if Moore continues to deny the allegations and nothing credible arises Trump will weigh in.
