Seriously, loony-Santoony?

Against the UN Convention on Persons with Disabilities??? It's a "direct assault on us and family," Santorum opined. Really? 125 countries have ratified this piece of legislation but we're against it because perhaps it could affect home-schooled kids?  Because passing it might violate US sovereignty? What does that even mean? What an awful human this guy is. He and the grotesque minions who voted with him. Despicable.
