I don't see why his position on the metric system is some kind of joke. Honestly, I think it's refreshing to see a candidate taking it seriously. This is something scientists have been pushing for a long time now, and with good reason. It's much better than the English unit system. I doubt he thinks he's scoring big political points by bringing it up so I assume his position is sincere. We lost a Mars orbiter because someone didn't convert inches to centimeters. It's not a trivial issue. The joke is that no one seems to care.
The METRIC system is great, it's Chaffee that's a joke!
