There are few reports of long lines today, and one jurisdiction I’ve been watching in particular is a fascinating case study in how to reduce voter wait times: Maricopa County in Arizona. Maricopa County is the most populous county in the state (it includes Phoenix and Scottsdale) and the fourth-most populous county in the nation. Between 2008 and 2012, it cut the number of polling places from 403 to 211, and long lines started to become a problem. During the 2016 primary, which saw hourslong wait times across the state, Maricopa had just one polling site for every 21,000 voters and vote centers there closed, on average, more than two hours late. At that point, and in response to a lawsuit, the county enacted a “wait-time reduction plan,” with a goal of having voters wait no more than 30 minutes to vote, on average. The plan included strategies such as hiring more poll workers, increasing the number of voting sites, and having backup equipment and ballots. It has been updated each election.

This year, the final plan included allowing voters to vote at any polling place in the county, rather than assigning each voter to a single voting location. The county also has a website where voters can check wait times before heading to the polls. We’ll need to wait until after the election to get a full sense of how well Maricopa County’s plan has gone, but so far it seems to be working: According to the site, the longest wait time is currently 25 minutes, at Surprise City Hall in Surprise, a suburb of Phoenix. Surprise, indeed!
