There is absolutely no doubt that John McCain joined with Democrat Senate Minority leader, Chuck Schumer and his Democrat low life caucus to bring down the Trump effort at the repeal and replacement of Obamacare. All one has to do to verify this act of treason, by McCain, is to follow the video sequence of gleeful, Chuck Schumer and his cheering/clapping, hate America, Democrat caucus, as McCain votes NAY. McCain is a traitor to the POTUS, Trump, the GOP Senate Caucus, the American people and, worst of all, the entire American nation.
He should be thrown out of office by the people in the state of Arizona immediately.
Can't be done. See a previous post about the litigation of attempted recalls of senators.
He can resign, die, be expelled by a two thirds vote of the Senate, or defeated in the next election. I would guess that death is the way in which he will leave office.
