Presidents: how many do we have? Ask Barney Frank.

President: n. CEO of the USA.
Congressman Barney Frank (D-MA), ever ready with the pithy quip says, “[Obama’s] going to have to be more assertive than he’s been. At a time of great crisis with mortgage foreclosures and autos, he says we only have one president at a time. I’m afraid that overstates the number of presidents we have. He’s got to remedy that situation.”
