voting by mail

The COVID pandemic has disrupted many aspects of our lives and there are concerns that turnout may suffer in the upcoming November elections. Voters may be reluctant to vote in person and social distancing precautions may increase the wait time for voters. Voting by mail has been proposed as a possible solution. Many states allow for all voters to vote by mail or at least allow some of their citizens to vote by mail if they are elderly, disabled, or will be out of the area during the voting period.
President Trump, among others, has rejected calls to allow for nationwide mail in voting during the pandemic due to concerns over potential voter fraud. Proponents of voting by mail argue that this system does not experience common or significant levels of voter fraud.
