Quite the Doomsday scenario. So, what do you suggest we do?
Perhaps, just oppose each dangerous initiative from Trump for damage control, and wait it out till 2020?
Since Pence will be a more predictable right-wing extremist, the major benefit of a Trump impeachment, protection from his impulsive and ignorant actions, would only lead to a more focused and disciplined attempt to trash the environment, rights of targeted groups, and concentrate power.
I wonder how many Trump voters are feeling good about him in office. Your Cambodia analogy seemed really strained. You really think farmers will take a Trump impeachment that seriously? Talk with farmers. Trump has never gotten his hands in the dirt in his life.
