Yes, it was during the Nixon administration that the left discovered that a soft coup was doable in the US.  Now, in the minds of the leftist media, anything a Republican President does is either questionable, or an impeachable act.

Something else the left does not admit to is that the North Vietnamese were terrified of Nixon and when he was replaced by Ford, they invaded, thus, the deaths of several million Vietnamese, mongs and Laotians can be laid at the feet of the left.
