It’s an unnecessary fear and reacting more to their hatred of Obama than any rational fear. At the same time, saying that he is on some sort of “nut wagon”.

I don’t think it’s wrong for the president to speak on education issues, you’ve just got to be careful about how you do it so you don’t look like you are using the public school infrastructure for a political purpose

That doesn’t sound like a guy who’s nuts. There’s plenty of actual crazies out there, no need to get crazy calling people crazy.
