Disappointing, but not unexpected. Wayne County's canvass was off by 30 or 40 votes out of 867,000.
If they didn't certify, the State Board of Canvassers certainly would have.
Wayne County also has about 1.4 million registered voters, when it only has about 1.3 million people over the age of 18 (not all of whom are citizens, either)... but nothing strange is going on there, right?
