He's angry. Most people balked at his claim that Cruz is an anti-Semite (he writes a journal about it regarding Cruz's "new york values" line) And apparently he was traumatized by the treatment he received in DU's primary forum...so......I'd say he's at the level of Jenny's boyfriend Wesley from Forest Gump, where he knocks her down and then later blames it on the war and the lying son of a bitch Johnson.
