Personally... if there's anything to the Epstein Ebebophile Island with Trump, I think to date it's been a case of political MAD, with Clinton's even bigger ties to Epstein and "partying" at the island.
However, if there really is some earthshaking shift, or something so smoking-gun in the new round of FBI investigation of Clinton emails by way of Huma and Weiner, it could be that either out of panic, or simply nothing to lose, they'll try to use it.
Should be interesting.
