Liz Cheney is truly sick. Her actions are what pathological narcissists do when their narcissistic image is challenged - as hers has been. She and Hillary are psychologically similar, and similarly dangerous.
Liz Cheney is no longer a functioning human. She is a fantasy of CNN and MSNBC, being whatever they want her to be. When they stop feeding her, she will disappear like a fart in a windstorm.
Liz Cheney should soon be irrelevant. Who cares what she says/thinks?
