Nixon was hated by the left from the time he was a Congressman from California and helped to expose Alger Hiss’s activities. They rejoiced when a mob in Venezuela stoned his car and were thrilled when he lost to JFK in 1960 and to Edmund Brown when ran for governor in 1962.
Naturally they were mortified when he won the Presidency in ‘68 and even more so when he won 49 states in 1972. They finally got him via the Watergate scandal when Republican leaders convinced him that he would not only be impeached, but convicted in the Senate. If you weren’t around, the Watergate hearings were must-see TV for months. The Jan. 6 Committee was hoping for the same thing, but it didn’t happen for them.
He was by no means perfect, but he did manage to acquire the right enemies. The left hated him as much as they hate Trump, only for decades longer.
Nixon was a piker compared to zero.
