Sen. John McCain (R-AZ) has announced that he will not vote for the Graham-Cassidy bill to repeal and replace Obamacare. He's likely killed it. Due to arcane peculiarities in Senate rules, this was the last opportunity to dump Obamacare without being stopped by a filibuster, until perhaps January of 2019.
Every Republican (including McCain) swore to vote to replace Obamacare. McCain is letting his pique with Trump get out of hand. If this flip-flop doesn't make McCain the RINO-in-Chief, I don't know what it would take.
Good people of Arizona, you really need to replace ol' John with someone who will actually act and vote like a Republican. He has become an embarrassment to you and to the party.
