And your natural inclination is to assume that turnout at public comment maps to those people most impacted by an issue. But that's not at all the case! Turnout maps to those most activated by an issue, which is a function of how much free time they have (public comment is generally wealthier and older) and how fearful they are of change (public comment biases sharply towards "no").
I'm fond of asking people locally here how many of them have even considering turning out at public comment opportunities to support new apartment development. I've never met someone who has, even though people here are broadly supportive of housing. But go to a Plan or HPC meeting: there's a line of commenters out the door opposing the apartments.
Public comment is antidemocratic.
