The Michigan Secretary of State does not expect final results from the presidential primary to be available until “early afternoon” on Wednesday as clerks work to count a historic number of absentee ballots.

Changes to voting laws passed in 2018 allow Michigan citizens to vote absentee for no reason. Secretary of State spokesman Jake Rollow said 804,216 absentee ballots had been cast as of this morning, a 60% increase from the 2016 primary.

“In terms of having all jurisdictions fully done and reported, I think we’re looking at early afternoon Wednesday at this point,” Rollow said on a call with reporters. “It would be great if it gets done before that. Given the workload that we see on people’s plates, we know that they’re doing their best to try and take all this on.”

Close to 1 million people -- 993,000 total -- requested an absentee ballot as of Monday evening. The number is close to the 1.1 million absentee votes cast during the 2016 general election.

Rollow said some jurisdictions that increased staff are doing “quite well” in processing absentee ballots received before Tuesday. Some clerk’s offices may not be able to deliver absentee ballots to be tabulated by a counting board until after the polls close, he said.

“That’s not all jurisdictions, some did not or were not able to staff themselves to that extent,” Rollow said. " While some counties may be able to report earlier than others, we are still expecting that it won’t be until sometime tomorrow, early afternoon we hope, that we would actually have all jurisdictions and therefore all counties able to actually report results."

Voters who already obtained an absentee ballot have until 8 p.m. Tuesday to return it to their city or township clerk’s office.

Meanwhile, some voters taking advantage of another change allowing anyone to register to vote on election day are experiencing long lines at clerk’s offices. Rollow said 7,198 people have registered to vote as of 4:30 p.m. Tuesday, causing lines to form in cities with a high number of college students, like Kalamazoo, Grand Valley, East Lansing and Ann Arbor.

Election-day registrations are quickly growing with just a few hours left before polls close at 8 p.m. The number of people who registered on election day jumped 52% in just two hours between 2:30 p.m. to 4:30 p.m.

Citizens seeking to report voter fraud can contact their county clerk, the Michigan Secretary of State office at (517) 335-3234 and/or the nonpartisan Election Protection Hotline at 866-OUR-VOTE.
