Put simply they are, at worst, possessed by real intelligent evil or, at best under, the influence of same evil. They are spiritually blinded and actually embrace the blindness in exchange for worldly gain.
This is always the result of denying God and making oneself their own god.
Pardon me for my faulty memory. Was it the funeral of Russ Feingold that foretold the insolent behavior of those in the Chamber? It was a funeral of a Democrat politician 5hat glorified him, and basked the Republicans openly as part if the ceremony. I remember the white eyed hatred of many, and Rush commenting on it for years.
The current Democrats are no better than a petulant child throwing a temper tantrum with no one to supervise or correct/punish them.
