Perhaps he's sincerely contrite and deeply ashamed of his disgusting display, but I find that pretty hard to believe. Perhaps he's playing the "Oh poor me" victim card, I can't really say.
What I can say is I have about the same amount of compassion for this Americans for Prosperity jackass that he had for the man with Parkinson's disease.
Karma's a bitch, man.
Not surprisingly, I can find NO mention of the incident, and certainly no condemnation of this man's actions, on the Americans for Prosperity website.
Stay classy, Americans for Prosperity.
