Illinois voters enraged after receiving threatening mailer containing their voting history

Chicago voters are angry after receiving mailers containing their voting history, as well as that of their neighbors.

What are the details?

The mailers were reportedly sent by the Illinois State Voter Program, according to WBBM-TV.

The org's mailers push residents to vote, and include their voter record since 2014. Voters' neighbors are also included on the mailer's list, and their personal voter information is also revealed on whether they voted during the last several elections.

A portion of the mailer reads, "What if your friends, your neighbors, and your community knew whether you voted?" and  later demands, "Do your civic duty: vote!"

The letter goes on in an apparent threat to send the letters out again and again "to your friends, your neighbors, and other people" if they do not vote in the 2018 elections.

Resident Kathy Stone was one registered voter who received the letter, and is not happy about it.

"I’m very angry at this. I have never, in all my years of voting, I have never seen anything like this," Stone told WBBM's Dana Kozlov. "If you’re going to do this to me, if you are going to threaten me to tell people that I’m not voting, why would I want to vote?"

Is this legal?

According to WBBM — who reports that the mailers are legal, as the group reportedly uses publicly available data —the Illinois State Board of Elections has been "flooded with complaints" about the mailers. James Allen of the Chicago Board of Elections told WBBM, "This is a pre-election day stunt to try and drive up voter turnout in that precinct or ward."

Allen noted that the action isn't illegal, "just creepy."

The Illinois state primary is Tuesday. The polls are set to close at 7 p.m.
