Why Is Newt "The Smart One"?

He has somehow fooled people even dumber than himself into thinking he's "the smart one" because he goes around saying he's smart while stamping his feet and shouting.  Yes, he's smart enough to know that stupid people will fall for his   book tour  presidential campaign, but being the classiest cast member of The Jersey Shore doesn't make you Jackie O. - XMASTIME

His "I'm smart" schtick appears to be appealing to the same demographic that wants to read Glenn Beck on George Washington and Bill O'Reilly on Lincoln.
