The seating capacity for a football game is 40,000. The TV angle only showed half the stadium and it was pretty full. So even if the other half was totally empty (which I doubt), you’re still looking at 20-25k when you count the audience on the grass. That’s a lot during a primary with 17 candidates in the field.
