That doesn’t bother him. As one of many among the corrupt, he is taken care of financially.
The way to get at corrupt persons like Flake is to arrest them on corruption.
He has a chance to leave DC in peace without incident.
POTUS and those around them have the goods on the corrupt members that are leaving and not running for reelection. Why are they leaving>? Because they have been told to leave peacefully or face consequences.
Flake will vote to confirm and then will leave.
The question for those that he lives among is will he try to fight another day? What will the people around him do if that happens?
He has to move. He is despised here. He may be able to make a life on the ranch, but he seriously couldn’t get elected here even with the full Morgan Church behind him.
