Detailed reports from the office of Wayne County Clerk Cathy Garrett show optical scanners at 248 of the city’s 662 precincts, or 37 percent, tabulated more ballots than the number of voters tallied by workers in the poll books.
Democrat Hillary Clinton overwhelmingly prevailed in Detroit and Wayne County. But Republican President-elect Donald Trump won Michigan by 10,704 votes or 47.5 percent to 47.3 percent.
Overall, state records show 10.6 percent of the precincts in the 22 counties that began the retabulation process couldn’t be recounted because of state law that bars recounts for unbalanced precincts or ones with broken seals.
The problems were the worst in Detroit, where discrepancies meant officials couldn’t recount votes in 392 precincts, or nearly 60 percent. And two-thirds of those precincts had too many votes.
State officials are planning to examine about 20 Detroit precincts where ballot boxes opened during the recount had fewer ballots than poll workers had recorded on Election Day.
Republican state senators last week called for an investigation in Wayne County, including one precinct where a Detroit ballot box contained only 50 of the 306 ballots listed in a poll book, according to an observer for Trump.
