Nixon was never impeached or convicted. Public pressure can build. Not that with a compliant press we expect that, but it’s possible, remotely possible, that he could be forced to resign rather than face impeachment much less conviction in the Senate.
Like you, I’m hoping for the public pressure angle to work. I’m also hoping months of accusations, investigations, and recriminations, regardless of outcome, will effectively halt his 2nd term agenda.
Yes, Nixon resigned rather than go through the impeachment, trial and conviction process. But he didn't do that until it was certain that he lose, that the House would impeach and the Senate would convict. Compared to Obama and even Lyndon Johnson, Nixon was an amateur. Petty theft compared to mass murder. But he was a Republican. Big difference.
Nixon, even though his price and wage freezes, creation of the EPA, and opening up relations with China might not back it up, was a Republican. The press killed him and he was an honorable man and resigned.
Clintoon, was humiliated, had his law license pulled, and was impeached by the house. And through all that the press minimized it all and he never resigned. He also happened to be a Democrat.
Now, what would happen to another Democrat President, and the first black President?
No, there is nothing, absolutely nothing, that will cause Zero to resign, and almost nothing, short of ordering the New York Times to close their doors, that would cause the press to call for his resignation.
(And even then, CNBC would probably point out the positive aspects of closing down the NYT and give Zero a pass...)
