At PPG Paints Arena in Pittsburgh on 4 November, teams of ushers were handing out signs that said: ‘Trump will fix it.’ They didn’t allow homemade signs because it was a safety risk, they said, though it also meant they could control what appeared in photos and videos. Seating was carefully orchestrated too: teams of workers wearing T-shirts with union logos and hard hats were positioned close to the stage, behind Trump, so the cameras would show him surrounded by cheering blue-collar supporters. Empty seats were kept out of frame, though there weren’t many of them. For weeks leading up to the US election, Democratic Party superstars took aim at Trump’s ‘weird obsession with crowd sizes’, in Barack Obama’s words. But the election result suggests a harsh truth: Democrats needed to do a better job of courting Trump’s crowds rather than dismissing them.
