Based on the present state of affairs, and assuming there are no further revelations, it looks like Roy Moore will outlast the outrage over the accusations, which he denies, that he molested a 14-year-old girl and assaulted a 16-year-old girl almost 40 years ago. Those serious accusations of criminality have been conflated in the media with non-criminal accusations that Moore dated teenage girls of legal age.
I say "assuming there are no further revelations" because I would not be shocked if more comes out. Moore's wife complained that the Washington Post is calling everyone the two of them have known for the past several decades, and certainly other major media are conducting similar searches. So what follows assumes there are no new accusers, and no additional evidence to support the current accusations.
