I agree. Trump should lay off the grade school level, ad hom attacks on McCain, regardless of the level of low-life political scum he was when alive. This isn’t 3D chess. It’s more like trying to play mumblety peg with the feet of a dead body.
McCain is being outed for his crimes. Justice should not be political or about what is to be gained or not gained by truth telling.
What McCain did was wrong and people need to know about it.
