Voting is a habit. In 2014, many states with the highest level of participation were also competitively close in 2016. Most recently, Michigan, where the election was closest in our last presidential election, “shattered” mid-term primary voter turnout. With a national popular vote, presidential elections would be competitive in every state and turnout would soar everywhere. The most meaningful way to increase voter turnout in midterms permanently would be to make every vote count equally in presidential elections.
