Michigan pollster accuses McMorrow campaign of killing unfavorable Senate poll

A prominent Michigan pollster is accusing state Sen. Mallory McMorrow’s Senate campaign of pressuring a state capitol news outlet into killing a survey of the heated Democratic primary.

The pollster, Steve Mitchell, told POLITICO the survey was conducted on behalf of Michigan Information & Research Service, an independent news outlet covering the state capitol that his firm regularly works with. But MIRS ultimately chose not to publish the survey after pushback from the McMorrow campaign.

The poll found McMorrow at just 6 percent ahead of the state’s pivotal Aug. 4 contest, far behind former public health official Abdul El-Sayed at 42 percent and Rep. Haley Stevens at 33 percent.

“The poll, in the eyes of the McMorrow campaign, understated their support,” Mitchell, whose firm Mitchell Research & Communications conducted and paid for the poll, told POLITICO. “And they put intense pressure on MIRS, and therefore MIRS decided that they weren't going to run the survey. That's their decision, and I support their decision.”

McMorrow has trailed the other two candidates in a number of recent public surveys, but 6 percent would mark a new low — a sign her campaign for the critical Michigan Senate seat may be mired in third place. McMorrow’s campaign told POLITICO the polling methodology was faulty and that its resulting memo was riddled with errors, including spelling her name wrong.

Kyle Melinn, a news editor with MIRS, said he killed the poll after speaking with the McMorrow campaign and other pollsters.

"I told Steve that the campaign did raise issues with the poll, and that they were pressuring me to not run the poll,” Melinn said in an interview. He added that after registering the McMorrow campaign’s concerns, he solicited the advice of other pollsters, and “didn't run it because I didn't feel comfortable with it." The other unidentified pollsters shared his issues with the poll, according to Melinn.

McMorrow campaign spokesperson Jackson Boaz said in a statement that “Voicing concerns about a poll isn’t a pressure campaign. They chose not to publish a survey that is deeply flawed.” Asked whether the campaign had asked MIRS not to run the poll, Boaz said, “MIRS chose not to run the poll because they agreed the poll did not meet their standards.”

Boaz said the McMorrow campaign reached out to MIRS after “we noticed odd things about the data,” including that 0 percent of Black voters were undecided in the race; 0 or 1 percent of voters in Detroit and its metro area were undecided while other parts of the state had undecided voters at 25 percent, 48 percent, and even 54 percent; and that McMorrow was at just 5 percent support in her home base of Oakland County.

Their suspicion — which they said MIRS confirmed — was that the poll allowed anyone to take it through an open link, rather than having access controlled to ensure a random and representative sample of the state.
