DFL Party officials have sent sample ballots containing the wrong polling place information to thousands of voters around the state.

The sample ballots include lists of DFL candidates running in the Aug. 10 primary, customized for the particular voter’s area. Also included is the name and address of each voter’s polling place. And in hundreds of precincts, that information is incorrect.

In response to questions from MinnPost, Andrew J. O’Leary, executive director of Minnesota’s DFL Party, said in a statement:

“The Party received a sample-ballot list with some polling locations that had not been updated. We have now received the updated list, and are contacting by phone those voters to whom the incorrect information was passed along.”

Party officials would not reveal who had provided the faulty list, and O’Leary declined to answer questions about his statement.

One party official said information was wrong in mailings sent to at least 8 percent of the state’s 4,000 precincts. That would be about 320 precincts, scattered around the state. But some sources estimated as many as 500 precincts could be involved. It’s not known how many people received the ballots with the wrong information or where they live.

Considered most likely to be affected by the mix-up is the Margaret Anderson Kelliher campaign: She’s the party’s endorsed candidate for governor and listed on the sample ballot with her running mate, John Gunyou.

Kelliher is involved in a tight three-way race for the DFL nomination in the primary with Mark Dayton and Matt Entenza, both of whom have spent tons of personal money in the race on television ads and mails. Kelliher’s campaign is counting on the support of DFL party members.

Jaime Tincher, Kelliher’s campaign manager, said this morning that she’s not worried that voters will be confused by the wrong information on those sample ballots.

“The DFL contacted us when they found out, saying they’d received a list with incorrect locations and wanted to let us know,” she said. “The folks in those areas will get phone calls, to ensure that they get the correct information. They’ll get a follow-up phone call, and we’re doing everything we can do to make sure they know where to vote.”

Asked if that might be a daunting task — finding those people and making the calls — Tincher said:

“Our field office makes 20,000 calls a day, so it won’t be too bad.”
