Today should be good for a couple hundred.

And in this case, because of the additional "international" angle that didn't exist with Watergate, it will take much longer.

bankrupted 6 times because of over playing his hand. His concentration is limited. With his obsessive-compulsive behavior in full blown out self destructive tornado...I predict sooner. Just my opinion.

...with an eye toward impeachment.

Still, there's so much unpredictable stuff that's happened, we might be on a Trump resignation watch ahead of the Watergate schedule of events if things get really deep and republicans revolt. There's no telling how antsy they'll get in advance of the midterms, and Trump has the consistency of bologna.

Although, as someone mentioned above, the thousand cuts is fun!

The Senate Watergate Hearings were formed in Feb 1973 and only began mid-May. The crucial revelations happened in Summer, 1973. There was no move towards impeachment until the Saturday Night Massacre on October 20, 1973. The following week was the first time that the House began impeachment proceedings. It would be ten months after that event that Nixon resigned. The House Judiciary Committee did not approve the articles of impeachment until July, 1974. That would be nine months after the House started the process.

Your timeline is entirely incorrect.
Here's some help:
Watergate 1973 Chronology

Note that John Dean's testimony before the Senate Watergate Committee begins on 25 Jun 1973, 14 months before Nixon resigns and 13 months before articles of impeachment were voted on in the House Judiciary Committee. Plus, there's the fact that Nixon resigned before his inevitable impeachment. There was no impeachment.

Instant gratification has gotten a lot shorter these days. Surely someone on DU will expect impeachment to start today. LOL.
