I'm reminded of all the various schemes that you see on boards like the Free Republic, whereby Hillary Clinton will maneuver herself into the presidency. These guys interpret every development on the Democratic side as the fulfillment of another stage of her machiavellian machinations (ex post facto, of course).
I've heard some loony conspiracy theories, but Hillary Clinton? I think that they're giving her far too much credit. I'm sure that the Freepers could come up with a strategy by which Chomsky would insinuate himself into the presidency - not a convincing one, mind you, but a strategy nonetheless.
So many things would have to change before Chomsky could become president. I can't see moderates on either side supporting him.
