Arguments based on voter participation overlook that voting is a statistical sample of the population. The people who don’t vote broadly break down roughly the same way as the people who do vote. And even to the extent they don’t, it’s risky to make assumptions about how they would have voted.

If you can generalize about non-voters, it’s that they’re broadly more anti-institution than voters—which is what causes them to put less stock in the institutional practice of voting. In the U.S. in the Trump era, that has meant that non-voters or infrequent voters support Trump somewhat more strongly than regular voters.
