The non-invitation and reprimanding of Trump rings a little hollow when you remember that Bush was a far bigger monster than Trump in terms of actual actions and arguably worse to McCain as well. Then there's Kissinger...
McCain was a portrait in contradictions, which he spun into an image of a maverick. He was attacked in the most ugly fashion by W in 2000, much worse than Trump, but he still supported Bush in 04 and attacked a fellow war hero in doing so.
He was a war hero and survivor, but a committed war monger.
He defended Obama's character but also attacked it.
He was mixed up in the 80s financial corruption, but then fought to reform campaign finance.
He hated Trump, but then voted with him plenty, worst of all for the tax scam.
I just can't see why McCain was so buddy-buddy with Bush, who continues to get rehabilitated for no reason at all. Painting?
