As we know only too well, Drumpf only cares about himself and that he is regarded and lauded for being successful, brilliant at business, rich, intelligent (high IQ is his go-to description for anyone he "likes") as well as being in perfect health and super virile (🤮) etc etc. So he could be more worried about evidence coming out from the Epstein docs that he was/is a complete loser/low IQ/failed businessman more than any underage sex stuff.
It is more than likely that there are abortions in his past, given his recorded proclivities... But even if they involved force, under age females, lives lost/ruined would they dent the MAGA and Repug support?
After typing all the above, perhaps the silver bullet that he truly fears IS evidence of a same sex encounter coming out? I just can't see it though...unless drugs were involved?
