Wow, that is a bit over the top.  What catastrophe followed Nixon's resignation?  None I can really think of.

This type of reaction to him would be comical if it was not so deranged.  

It's policy implementation that leaves lasting scars on our country.  Think about 3 trillion dollars spent on 2 wars over the past decade.  Think about the morass our healthcare system is in due to either ACA or Republican meddling with ACA whichever your believe.

Given the sheer volume of escalating hyperbole from the left and the nevertrumpers, they're going to run out of words soon and have to start making them up.
