As to point #4: Trump will use the issue of her treatment of Bill Clinton's accusers against her. This is a double winner for Trump, who can call out the entire Feminist Left along with her. How will Hillary look if her participation in a smear campaign against Bill's accusers becomes a debate topic? Trump won't be afraid to use this issue, and it WILL resonate with SOME women who would ordinarily vote for Hillary.
I have a strong suspicion that if and when Trump tries to unload that gun in Clinton's direction, not only will it backfire, but he'll be inundated with an avalanche of his own affairs.
