Let me propose a couple of sub-categories:
For AAH of the Year, Category "Certifiable Creep" - Jerry Sandusky, hands down
For AAH of the Year, Category "Political Turd" - Slo Joe
For AAH of the Year, Category "Incompetence Personified" - John Boehner
For AAH of the Year, Category "Evil Incarnate" - Adam Lanza
For AAH of the Year, Category "Skidmark" - Julian Assange (although he gets street cred for making a laughingstock out of most of the western powers in his ducking various charges levied against him)
For AAH of the Year, Category "Political Hack and Shuck 'n Jiver" - Hillary Rodham Clinton for Benghazi. Honorable Mention to Eric Holder for F&F
