Juan McCain knew he was the designated loser to the anointed one.
He hated Sarah because she wanted to fight and win.
She was hung out to dry afterwards. McCain did not deserve what she brought him. I hope she recovers well from this new turn in her life. I hope they both do, they've been through crap very few of us could stand to wade through.
Sarah endorsed McCain for his 2010 reelection but then got on board with Trump early in 2016, a move that must have made the irate McCain even more irate.
