Watergate started out sounding like a political witch hunt. Too bad Nixon didn't do what he did in today's atmosphere, he would have skated for sure.
I grew up during Watergate. You know what most people said at the time? Nixon didn't do anything any of his predecessors didn't do.
Nixon was forced to resign because he had few friends in his own party. Between his participation in McCarthyism and some of the other shit he pulled in his years in office, he was just unlucky enough to be caught in the perfect storm of scandal, bad economy, and a country pissed that we had just lost our first war in memory. Watergate by itself wasn't fatal to Nixon, it was Watergate on top of everything else.
Nixon could have ended Watergate in Five Minutes. He didn't order the break in. He should have fired the people who did and apologized for it. Instead, he tried to protect his guys.
The thing is, the reason why you've never had another Nixon is that everyone learned from Nixon's mistakes. You've had enough scandals that were just as bad as Watergate, but in every case, they were handled. Not just Zippergate, but Iran Contra, the Plame Affair, etc. Find a fall guy to fall on his sword.
So while Huma might end up being the Fall Guy (or gal) in this, you guys aren't going to ever touch Hillary. Deal with it.
