We know this because we actually surveyed the protesters. Here’s what we found.
How we surveyed the crowds
During the RNC, our team of 14 researchers covered all permitted rallies, marches and the official protest areas outside the convention. This included the March to End Poverty Now, several Stand Together Against Trump marches, rallies and demonstrations, and the pro-Trump America Unity Rally.
Our survey protocol was based on the Caught in the Act of Protest: Contextualizing Contestation project. The protocols designed by this project have been implemented at dozens of protests in Europe and South and Central America. In Cleveland, we used several techniques to sample participants in various forms of demonstrations, from stationary crowds at protest sites to marches down the streets.
For example, in marches, our team leaders would walk along with the crowd and count a certain number of rows back and then a certain number of individuals in to select the participant (the number dependent on the size of the march). They would then send an interviewer in to survey that participant. The team leader then counted back and over again to select the next respondent, who would be further down the march and further into the crowd. This process continued until the team leader had counted enough to span the width of the march. They would then continue counting rows further down but now count in going back across the columns of the march.
This created a zig-zag pattern in which all participants had an equal probability of participating. This method allowed us to capture a representative sample of those participating in public events outside the convention.
Trump was not the only reason people came to demonstrate.
A large group (part of the “Other” category) did not believe that a single issue could be highlighted and saw many issues as interconnected, with capitalism often cited as the root cause.
The Republican Party was not the focus.
Traveling far to protest.
The lack of support from Cleveland residents is probably part of the reason the protests were so small throughout the week. Without local support, larger crowds are more difficult to create and to sustain.

We would like to thank Pennsylvania State University, in particular the McCourtney Institute for Democracy and Lee Ann Banaszak, and the University of Pennsylvania, especially Daniel Gillion, for the financial support to make this research possible. We also would like to thank our surveyors for braving the crowds and not freaking out when we warned them that they might get tear-gassed: Parker Anderson, Mackenzie Cornell, Tyler Cousins, Aviva Doery, Nick Filingeri, McClain Fultz, Jessica Lee, Hannah Magoveny, Jacob McCall and Ilayda Orankoy.
