The Sad State of Voting, in 5 Visuals

Wisconsin voters are casting ballots Tuesday in perhaps the most consequential state presidential primary in the nation. Historically, candidates who’ve won Wisconsin have gone on to become their party’s nominated leader in every election since 1968, save for 1984. Arizona’s primary will likely be heavy on Wisconsin voters’ minds: The confusion and frustration faced by voters there on March 22 was bad enough that the U.S. Department of Justice is now investigating election failures in the state.

Wisconsin mirrors Arizona in a lot of ways, namely that both states have been heavily mired in voting rights litigation—Arizona for its proof-of-citizenship voter registration law, and Wisconsin for its voter ID law. As many as 350,000 people lack the photo ID needed to vote in Wisconsin as the state holds its first major election where such identification will required. Meanwhile, a ProPublica investigation has found that the state has failed to fund education and outreach efforts around its voter ID law.
