[Michael P. Lynch offers an incredible thought experiment:]
Suppose I offer, at no charge, to drop a drug in the water supply that would cause almost everyone in the country to vote like you this November. You would probably feel at least a little bit tempted to take the deal. Presidential politics is a matter of grave import, after all. Still — many of us would hesitate, and rightly so. There seems to be something really wrong with manipulating people to believe things even when the stakes are high. We want to convince our opponents, yes, but we want them to be convinced by our reasons.
