One option is for Comey to say “There’s nothing there.” The other option is there’s so much dirt, and too many people know about it, that even Comey isn’t afraid of the Clinton/Obama machine anymore. I hope it’s the later.
If it is, don’t be surprised if Hillary becomes seriously ill and will be hospitalized in a private care facility never to be heard from again. But she may still be “elected” the first woman president. She just won’t take the oath.
It has to be the latter. He would never re-open it if it were not significant.
