I don't have any bumper stickers on my car. It's not that I have nothing to say- it's just that I feel a bumper sticker represents an open invitation to rebuttal by people with baseball bats. And I've seen some of the hostility that's out there for me. I can read.

Anyway, not so long ago I found myself in a drive-thru at a McDonald's behind one of these boats people used to drive around without getting all defensive, and she's got this bumper sticker: "JIMMY CARTER IS NO LONGER THE WORST PRESIDENT WE EVER HAD." Oh, I'm sure the folks from the carter administration take that as a great comfort.

Besides, for all but the most tragically thinking impaired it should be patently clear that Jimmy Carter wasn't the worst president we ever had. He wasn't even the most ineffective or the most unpopular. Anyone with even a rudimentary understanding of American History knows this.

But it's my job in this life to shake people up a little. The woman driving this car was clearly in need of this service. So I rolled down my window. "You're right." I shouted cheerily. This sort of thing never fails to get people's attention. "Jimmy Carter wasn't our worst president." She stuck her head out the window. "It was Warren G. Harding."

Her expression turned from bemusement to consternation and she disappeared into her car and squealed out of the parking lot. So please, if you're going to engage in political debate, save me some trouble. Do your homework. Know your history.
