USP Monitor estimates 28,500 at Flávio Bolsonaro rally on Paulista, down 32.5% from Sept 7

A USP crowd monitor estimated 28,500 attendees at a Flávio Bolsonaro rally on Avenida Paulista, 32.5% fewer than the 42,200 recorded at the September 7, 2025 event. The lower turnout suggests waning mobilization capacity for the Bolsonaro political movement ahead of the 2026 election cycle. The estimate is from an academic monitor and may differ from police or organizer counts.
