Detroit elections officials waited several days to deliver nearly 100 poll books to Wayne County officials charged with certifying the presidential election, newly released documents show.County clerk officials on Thursday released a memo to State Elections Director Chris Thomas that said 95 poll books from the 662 precincts weren t available at the start of the canvass, which began the day after the Nov. 8 election. Five of those poll books, which contain the names of voters and ensure the integrity of elections, were never delivered to county canvassers and presumably remain missing.The revelation comes atop other irregularities that have prompted a state audit. Among other issues, The Detroit News reported this week that voting machines registered more votes than they should have in one-third of all city precincts. I m not happy with how Detroit handled this election at all,  said Krista Hartounian, chairwoman of the Wayne County Board of Canvassers, which certified the election. We had been seeing improvement, but this one was different. This one was off. Canvassers compare poll books with printouts from voting machines to ensure the number of people who signed in to vote match the number of ballots cast.In heavily Democratic Detroit, the numbers didn t match in 392 of 662 precincts or 59 percent. The discrepancies emerged during a statewide presidential recount that began last week and ended Friday following a decision by the Michigan Supreme Court.It s unclear how many extra votes were counted in Detroit. That s because tallies were off by five or more votes in 52 Detroit precincts, but county officials will not release the exact number of discrepancies in each precinct.Read more: Detroit News
