The ability to participate in free and fair elections is arguably the most essential American right. Yet on Jan. 6, 2021, the nation watched as a mob overran the Capitol. In an act designed to interfere with the peaceful transfer of power from one president to the next, they attacked law enforcement officers who were there to protect the building and members of Congress inside. Rioters desecrated the Capitol. Our vote and our democracy seemed fragile that day and in the days that followed.

Now, President Donald Trump is trying to create a role for the president in running and overseeing elections. That’s not how the Constitution works.

The effort to interfere with the November midterms isn’t going to consist of a single, dramatic event on Election Day. It is what we are already seeing: a combination of efforts by Trump and his supporters to make it more difficult to vote, to create confusion about who is eligible to vote, to pressure state and local officials, and to manufacture uncertainty. As Jan. 6 proved, distrust among the American people makes it easier for an administration to contest election results they don’t like. And the Trump administration is doing all of this with an eye toward shifting as much control over elections as possible from the states to the federal government.

We can already see where pressure is being applied to voters and election officials, and we can identify the kinds of problems that are likely to arise.

You don’t need to be a constitutional law scholar to make a difference. It just takes a desire to be useful, to engage in democracy and become a participant, not a bystander. Know your state’s rules and deadlines for registering. Research whether you can vote early or by mail. Help the people around you, who may be less informed, do the same. Volunteer as a poll worker if you can. Volunteer to do election protection work if you are a lawyer, law student, retired lawyer or simply someone willing to be trained.
