Nixon thought he give away the store and win reelection, and he did take 49 states! He didn’t know that he had fallen into a trap set by the American people and their media.
I'm aware of staggering 'Rat hypocrisy and boo-hooing about all the issues that came up, which the 'RatMedia had tolerated as normal practice when the inestimably snaky FDR and LBJ had been the doers, and their hypocrisy and ruthless mendacity in contesting and pursuing Joe McCarthy literally into his grave.
I'm unaware of any popular complicity in "bagging" Nixon; that was a MediaRat operation exclusively.
I remember at the time that I was in graduate school, and it wasn't until James McCord began to give testimony that the scandal attracted any wide public attention; and things didn't go kaboom until John Dean appeared before the committee in March, 1973, nine months after the break-in.
