I have been told the counting stops when there aren't enough remaining provisional and absentee ballots to change the outcome. It's the law of diminishing returns. It isn't worth the money to keep counting when it won't change the outcome. As close as MI is they are having to finish the full count.
As I understand it, the MI Secretary of State has announced that all votes have been counted. While it is close, its somewhat odd that New Hampshire is MUCH closer, about 1000 votes and the networks have no trouble declaring it for Hillary.
“I have been told the counting stops when there aren’t enough remaining provisional and absentee ballots to change the outcome”
Well, you were told wrong. Most states have multiple statewide elections besides President, including many like Colorado, with a large number of initiated ballot issues. Each of these issues is independent of the other and very few track with each other, so there’s no way to stop counting ballots because THE outcome won’t change because there’s not a SINGLE outcome but many being counted, so what you “heard” is completely ridiculous.
