Well, there are any number of 'real world' examples where the Ds didn't pull the same shit that the Rs did.
How many times did a D controlled Senate hold confirmation hearings for a SC appointee?
The same false equivalence that Trump applied to the Nazis & KKK in Charlottesville ("there are fine people on both sides) is becoming the last refuge of the Trump supporters.
To pretend that the Ds would embrace corruption and criminal behavior to the degree that the Rs have is to ignore the lengths & depths (depths mostly) that the Rs have gone to in recent years to obtain power.
Purging voter rolls, Pretending there's voter fraud to justify requiring ID to vote, gerrymandering, now promoting blatant Russian propaganda.
Its truly disgusting.
And one of the reasons that I will never vote R again in my life.
