@blatham,
Nixon’s impeachment, resignation and period of public disgrace is a shaky example of justice being done to the rich, white and powerful.
As Izzy pointed out, Nixon was pardoned and even achieved a warped sort of elder statesman status before he died.
So, besides what happened to Nixon, it’s really hard to see what other basis you would have for a lack of cynicism regarding Trump’s future.
What? Faith that history’s arc bends toward justice? Faith in Merrick Garland?
Really, what?
