In a city with a history of air quality issues, the event kicked off with tightly scripted festivities, even as outsiders raised concerns about a team member’s relative youth. A massive show of police force was present to minimize any potentially embarrassing protests. The theme of the day was “One World, One Dream.” Oops. That was the Olympics. The theme of the day was “One Nation,” but other than that, everything else I wrote also applied to Monday’s opening of the Democratic National Convention in Denver.
