AT MIDDAY, BY the time the “No Kings” march in Chicago was due to start, so many people were squashed into Daley Plaza, in the city’s downtown, that it caused a sort of gridlock, with protesters unable to march in any direction. There were a few stirring speeches—for those close enough to hear, anyway—but mostly people milled around enjoying the show. Some came in fancy dress: furries; Mexican wrestlers; clowns and two men dressed as cardboard tanks. Some carried megaphones. The communists, with hammer and sickle flags, were well prepared; the families with small children on cargo-bicycles less so. What united them all was disdain for Donald Trump.
