Hillary had to endure being the "woman scorned" and still had to put on her "brave face" in public, there is no way in hell she is going to let that happen when it's HER name on the door.
As far as Bill being pissed when Hillary lost, you said it yourself "he really came across as wanting Hillary to win" Bill is one of the all time best liars in all history, and I say this as a compliment. Of course he came across that way, and he will come across that way when fate intervenes on her path to the White House this time too.
I doubt Hillary gave a fuck about being cheated on, what she gave a fuck about was having to be "that woman" the woman who was cheated on, the embarrassment was what she hated, not Bill boinking an intern, hell it wouldn't surprise me if Hillary wasn't doing a couple of interns herself, but if she has, she was smart enough not to get caught.
Also keep in mind that I am not talking about publicly sabotaging her with anything that could ever lead back to him. Keep in mind all those hundreds of millions of dollars raised by the Clintons he is responsible for as well. If Bill overtly sunk Hillary's chances to be POTUS there would be hell to pay and Bill knows that, but I would bet my last dollar that Bill knows where all the "bodies are buried" and he will be just as shocked as the rest of us when some "ugly truth" about her comes to light, but I bet you something along those lines is going to happen. I further suspect that he is hoping it happens without him having to cause it, but if it doesn't happen on it's own, I think he will give the truth a "nudge" lol
