It didn't shock me, I expected it. It was 'his turn' after all. It did, however, piss me off and turn me against the establishment wing of the GOP. Today that's all Republicans except Donald Trump, The House Freedom Caucus and Tom Cotton.
Cotton is good on a few things, but he's a disciple of McCain, Graham and the neocons when it comes to mongering perpetual war. So is Rubio.
What is scary is that Rand Paul was the ONLY one to stand up to this insanity. He also kept Georgia out of NATO.
