"I thought Nixon was the worst President we had ever had, save only perhaps Andrew Johnson"

This quote by Stephen Ambrose is a reflection on the legacy of 2 of the most questionable presidents in American history. By comparing Richard Nixon to Andrew Johnson, Ambrose is suggesting that Nixon was the worst president given that Johnson. This comparison implies that Nixon was an especially bad president, as Johnson was the only president to be impeached. Ambrose is likely describing Nixon's participation in the Watergate scandal, which led to his resignation from workplace. This quote likewise suggests that Ambrose thinks Johnson was a particularly bad president, as he was the only one to be impeached. This comparison implies that both Nixon and Johnson were particularly bad presidents, and that Nixon was the worst because Johnson. Ultimately, this quote acts as a reminder of the significance of holding presidents liable for their actions, and of the consequences of governmental misbehavior.
