Obama doesn't have to bone up to answer questions like that. He just turns on the automatic Socialist spew machine. It's been programmed into his head since childhood. It's why he sounds so droning and platitudinous. Few specifics - nebulous, mushy, indistinct.
The man can talk fast, but when you're done listening to him, you sort of blink and wonder what the heck he just said. It's because it's all mush. Just like his head.
Obama already has talked about education. Get back to Libya etc.
