Before we turn to the upcoming Democratic National Convention, which begins Monday in Chicago, I have to make one observation about the Paris Olympics, which just ended: Is there anything more bizarre than artistic swimming? I am amazed by the swimmers’ athleticism but terrified by the way they look before diving in. That makeup makes them look like homicidal clowns. The nose clips don’t help much, either.

Now, in an admittedly tortured transition, let’s talk about the Democratic convention. It is easy to dismiss these national conventions, Republican and Democrat, as blowhard nonsense, because they are blowhard nonsense. Blowhard will be on full display in Chicago.
