DETROIT (AP) — A judge declined to put former Detroit police chief James Craig on the Republican ballot for Michigan governor, the third candidate to lose a court challenge after election staff said campaign petitions were marred by fraudulent signatures.

It’s a remarkable setback for Craig, who has high name recognition in Southeast Michigan and retired as Detroit’s top cop last year to make his first run for office.

Court of Claims Judge Elizabeth Gleicher said she must abide by a Michigan appeals court decision released Wednesday that kept two other Republicans, Perry Johnson and Michael Markey, off the Aug. 2 ballot.

Gleicher’s opinion, dated Wednesday but released Thursday, also cited other reasons.

There appears to be no dispute that fraudulent signatures were turned in by paid circulators, though there’s no evidence that the candidates were aware of the scam. In a court filing, attorneys representing the Board of State Canvassers called it an “unprecedented situation.”

The candidates were declared ineligible last week as the result of a tie vote by the board. State election staff said Johnson, Craig, Markey and two others didn’t meet the 15,000-signature threshold because of fraudulent signatures.

In Craig’s case, election staff said he appeared to have only about 10,200 valid signatures after subtracting 9,879.

He argued that the state had an obligation to go line by line, comparing signatures to the eligible voter file before striking them. Only 20% of the suspicious signatures were formally checked.

But the appeals court said that wasn’t necessary.

“The board … had a clear legal duty to investigate, but it did not have a clear legal duty to conduct a comparison of each fraudulent signature against the qualified voter file,” the court said in a 3-0 opinion in Johnson’s case.

Five other Republican candidates have landed a ballot spot, including Tudor Dixon, a former conservative TV news host who has the backing of Betsy DeVos, who was head of the U.S. Education Department during the Trump administration.

The winner will face Democratic Gov. Gretchen Whitmer in the fall.
