Listen to Pierce again; "He's talking a private language, to himself, like crazy people do....."

There seem to be only two possibilities; either Obama is in fact "crazy", meaning he is certifiably detached from even a scintilla of reality, or he is cunningly trying to drive the rest of us crazy by standing before us, chin jutted into the air, and seriously proclaiming for the umpteenth time what we all know to be pure claptrap.

I can think of no third possibility
