Local election offices then send the final results to a board for certification. Such boards are typically bipartisan, their members either elected or appointed by county leaders.
Barring an obvious problem with the count that could change the result of the election, the board then approves the vote tallies before sending them to the state for final certification. That's usually done by a state canvassing board, the secretary of state or a small group that might include the governor and other state officials.
From there, federal law requires governors to prepare official certificates to report the popular vote in their states. These documents are often signed by the governors and must carry the seal of the state. A copy is sent to the archivist of the US.
WHAT HAPPENED THIS TIME?
In an extraordinary move yesterday, two Republican members on Michigan's Wayne County Board of Canvassers voted against certifying of the county's votes — then abruptly reversed course amid heavy criticism.
Explaining the initial vote, a Republican member of the Wayne County board said poll books in the majority-black city of Detroit were out of balance.
But a Democrat on the board noted the issues were the result of routine "human error," and the Republican's claim drew complaints of racism from Democrats and election experts who also noted there has been no sign of widespread voting fraud in Michigan or elsewhere.
And the results weren't even close: President-elect Joe Biden beat Trump in Wayne County by a more than two-to-one margin and won Michigan by 146,000 votes, according to unofficial results.
SO, WHAT'S THE DAMAGE?
Even though the Wayne County votes were certified in the end, the incident is likely to cast more doubt about the election's legitimacy among Trump's supporters.
It also could help galvanise Republicans elsewhere to look for ways to delay making Biden's victory official.
