In this critical election, Americans are busting all records for early voting and voting by mail. Yet, over 700,000 Americans have the right to vote but many are denied that right not only in this election, but in every election. An average of 746,000 Americans is held in local jails, most of whom have not yet been convicted of a crime or are held only for minor offenses.

Many of these voters are jailed simply because they are poor and cannot make bail. Yet in many jails, they are denied the right to vote -- either because officials are confused about their eligibility, or because they have no timely access to registration and absentee ballots, or because they have no access to the voter ID information that many states now require.

This form of voter suppression is a social injustice and a civic indignity. Not surprisingly, it disproportionately impacts African Americans, Latinos and the poor. It is part of what Michelle Alexander has called the new Jim Crow, the use of mass incarceration to strip minorities of their right to vote.

A new report, entitled "Eligible but Excluded: A guide to removing the barriers to jail voting," has been released by Prison Policy Institute and the Rainbow Push Coalition, which I lead. It details the eligibility of prisoners under various state laws, the obstacles they face to exercise their right to vote, and what activists, state and local officials and prison and election officials can do to rectify that right. Even now, two weeks from the election, prompt action could empower many to vote.

The obstacles erected to make voting difficult in this country are particularly hard for prisoners to surmount. Separate registration forms and dates can foreclose voting for those held in jails during required early registration dates. Voter ID laws hit prisoners who are often stripped of their ID papers when incarcerated and find that jail IDs are not accepted by election officials. For Cause absentee laws too often do not include incarceration as a cause justifying voting by mail. Jail mail and internet are too often slow or unavailable. Jail churning -- most of those in jails are there for short periods of time -- mean that many will find themselves in different addresses for registration or for voting.

State and local laws reforms are essential. Same-day or automatic voter registration is invaluable not only for prisoners but for most Americans. State law could designate jails a formal voter registration agency under the Motor Voter Law, as Rhode Island has done. Election officials could designate jails an official polling station, with voting booths and computers available on site. Activists and agencies like the Public Defender Services could run voter registration and get out of the vote operations targeted at jails.

In Illinois, Gov. JB Pritzker and Lt Gov. Juliana Stratton have passed legislation that sets the standard for reform. It requires county jails and election officials to create a process that allows eligible detainees to cast a ballot. It designates Cook County Jail -- the largest in the country -- a temporary polling place so detainees can vote in person. It mandates providing a voter registration application and notification of their voting rights to every eligible detainee leaving a jail. These are reforms that should spread across the country.

The right to vote is the defining right of a democracy. American history has been marked by the struggle to extend that right -- to those who weren't landowners, to women, to those old enough to be drafted. The civil rights movement, led by Dr. Martin Luther King, understood that the right to vote was essential to the struggle for equal justice for all.

The massive turnout expected in this election will lay bare all of the ways that states -- which still have authority over voting -- have conspired to make voting difficult, particularly for working people who can't afford to take time from work, or poor people who find the various obstacles difficult to overcome. Facilitating voting -- the fundamental right in a democracy -- should not be partisan. Sadly, it has become that as those fearful of the majority seek ways to suppress the vote, to undermine the election results, to sow fear and confusion. It is long past time for national reforms to ensure the right to vote. That reform effort should include the hundreds of thousands held temporarily in jails who still have the right to vote.
