I'm so inured to the idea of my fellow voters stupidly falling for everything that I often find myself kind of happily confused when some transparently cynical ploy fails. This has happened only a few times on major (non) issues that I remember -- the Clinton impeachment and the Terri Schiavo episode are the major ones.
It's too early to be confident, but I'm hoping that maybe the gas tax mess will be another episode of this kind. If the relevant points can be gotten into circulation -- the oil companies eat up more than half of the tax cut, and this is a dumb short-term fix that does nothing to address the deeper problem -- it's possible that a political debate will actually be won by educating people so they come to have the right views on policy. Weird.
