Stadium rallies played an important role in Donald Trump’s campaign for president. They gave Trump the chance to hold court and bask in the glow of an audience of admirers. And they gave his supporters a chance to feel the sense of solidarity that only being around like-minded people can bring.

Since becoming president, Trump has continued the practice of holding campaign-style stadium rallies. In June, he held a large one in Cedar Rapids, Iowa, where he mused on a variety of topics, from a recent Republican win in a special election for a congressional seat in Georgia and the next steps he would be taking to Make America Great Again, to, of course, the size of the crowd.
