Organizers encouraged people to participate in "#March4Trump" rallies across the nation on Saturday to show support for the president. In a few places, there were pretty good crowds. Like Nashville, where it was probably fair to say there were "thousands," and also in Florida.
But even the president probably won't claim they were "the biggest crowds ever." For example, the Denver 7 News sent out this: "March4Trump rally brings dozens of supporters to Colorado State Capitol." In pictures from other capitols, the crowds are best described as "sparse." The Huffington Post rather cruelly headlined its article about it as: "Tens of people rally across the country for March4Trump."
