McCain needs to be censured and removed from his leadership positions...however I do not believe the Senate GOP its current configuration has the courage to do so.
Until the voters stop rewarding such treachery, it will continue. One remedy would be to send home GOP Senators who oppose Trump, even if it means their replacement is a Dem.
In any event, change will likely have to come from the outside
McCain is my senator, and I am totally ashamed. But what can we Arizonans who love Trump do? McCain’s phone lines are always busy, emails always get rejected, and if you go to a local office, the office is always closed. What can we do? This @sshole is bunkered in good.
