Let me say I think the United States should adopt the metric system. I mean, who wouldn’t love to drive 100 on the interstate? Most of the conversions are easy. A gallon is basically four liters. A meter is about a yard. If Starbucks made the venti slightly bigger, it would be half a liter, We could call it a “half,” and you could order a half-caf half with half and half.

But I digress. I realize I am in the minority on this one. That is why I was slightly amazed to see that some guy from Rhode Island (or is it Connecticut?) thinks he can seek the Democratic nomination for president on a platform that includes adoption of the metric system. Mr. Chafee, whose dad was such a Republican that he named him Lincoln, seems to be a little unrealistic about a lot of things. But coming out for metrics may be the goofiest move we have seen yet in what is shaping up as a highly entertaining campaign season. Wherever she is hiding from the press right now, Hillary Clinton must be smiling.
