Early voting is underway in Tennessee, where residents are voting on Amendment 1, a ballot initiative to decide whether state lawmakers will have the power to enact, amend, or repeal laws regulating abortion.

Local media is reporting, however, that some voters have received misleading information about Amendment 1 and that there have been cases of voting machine irregularities.

There have been at least three incidents involving voting machines that changed “no” votes to “yes” for people voting on Amendment 1. Election officials have dismissed at least one of the reports as “voter error,” according to reporting by the Tennessean.

Meanwhile, the American Civil Liberties Union of Tennessee has raised objections to poll workers distributing a voting guide—created by Rep. Kelly Keisling (R-Byrdstown), a state lawmaker with a consistently anti-choice voting record—that gives biased information on constitutional amendments, including Amendment 1.

The guide says that voting against Amendment 1 means that “you are saying that you think there should be fewer restrictions on abortions and that abortion clinics do not need to be licensed or inspected.”

The voting guide also says that a vote for the amendment means that “you are saying that there should be some regulations on abortion such as, licensure requirements for abortion facilities and stopping late term (partial birth) abortions.”

Hedy Weinberg, executive director of the ACLU of Tennessee, wrote a letter to the Tennessee Coordinator of Elections Mark Goins responding to news of the guide, which said the organization is “very troubled about reports that poll workers are distributing misleading and clearly partisan information concerning the four ballot initiatives.”

Goins responded by sending letters to each county reminding election officials that the distribution of materials including explanatory language on ballot measures is prohibited.

Anti-choice activists campaigning for Amendment 1 also are lobbying state lawmakers to pass legislation that would require abortion clinics to meet the standards of ambulatory surgical centers.

The ambulatory surgical center requirement, a medically unnecessary provision, was also passed by lawmakers in Texas as part of an omnibus abortion law. The U.S. Supreme Court recently blocked Texas from implementing the provision while the law faces a legal challenge by reproductive rights advocates.
