Jeff Flake lives up to his name...
He was never a yes vote to begin with. They will have to win with Collins and the Cowski. Flake wants to go out as his hero McCain would, as a backstabbing POS. How did Arizona manage to produce two of the biggest backstabbing aholes to ever claim to be Republicans, much less conservatives and amazingly at the same time!
Since he is not running again McConnell should make it clear to him if you return as a lobbyist you will persona-non-grata to the Republicans in the senate. If you lobby for a position we will not be doing business with that lobbying firm and it will hurt their position.
