Counties with largest turnout increase and decrease from 2016

This is a category where it didn’t matter if a county was urban or rural —almost all saw a bump in registered voter turnout compared to the 2016 general election. But three counties (Imperial, Tulare, and Plumas) actually reported decreases in turnout, even as they saw higher than average registration growth. An Imperial County spokesperson said, “there were also many of our voters that were not accustomed to receiving mail-in ballots.” In Plumas, a BallotTrax program confused voters by sending canned messages about polling places, despite having none.
