Transterrestrial Musings gives two different ways to measure the crowd; the first one estimates between 240K-320K for the marchers and the second estimates between 330K-500K at the Capitol itself. Either way: use this as your baseline for what an actual populist, grassroots protest looks like. I mention this mostly for the Other Side, who seem highly incensed that we’re making this sort of thing look easy.
Which it is, actually: you just have to be on the side of righteousness, that’s all.
