Amid the COVID-19 pandemic, we must prepare for the possibility that traditional in-person voting will be more difficult for many this year. Voting by mail keeps voters safe while preventing disenfranchisement.
Multiple states already have vote-by-mail. Colorado, Hawaii, Oregon, and Washington conduct their elections almost entirely by mail — offering successful models for how it can be implemented around the county.
In 2016, more than 23% of voters cast their ballots by mail. There is already a significant precedent for vote-by-mail, and many voters are familiar with the practice.
Vote-by-mail improves voter turnout. States that allowed vote-by-mail had, on average, a 15.5 percentage point higher turnout rate than states that did not in 2018.
There is no evidence that voting by mail results in significant fraud. As with in-person voting, the threat is infinitesimally small.  As Sen. Michael Bennet of Colorado reminded President Trump after he opposed vote by mail on fraud grounds, “Mr. President, we’ve had vote-by-mail in Colorado for years. We don’t have fraud. But we do have the second-highest turnout in America.”
