Tracy Wimmer, a spokesperson for Michigan Secretary of State Jocelyn Benson told ABC News: "We're still looking at some time tomorrow, but we really don't have a guess of when."

"There are places that were able to do their absentee ballot tabulations much quicker than expected, but there are still some places that are lagging behind."

In Detroit, for example, of the 180,000 absentee ballots that were cast as of early Tuesday evening, 120,000 have already been counted, Wimmer said.

"Results are going to be coming out in varying ways and at varying speeds," Wimmer said," but it's important not to read into any of the results that are coming out until we have final results."

In Michigan, only 16% of the early vote is in with 49% of the expected vote in.

One of the most decentralized election systems in the country, Wisconsin state officials have repeatedly told ABC News that they expect full statewide results could come in the early hours of Wednesday morning, though everything is reported on a county level.

In Milwaukee, Wisconsin's largest city, officials expect results at 4 a.m. CT.

In Milwaukee County, as a whole, results will be an hour later.

In Brown County, clerks office told ABC News that results will come in sometime between 3 a.m. and 7a.m. CT. An estimated 0% of the early vote is currently in with 62% of the expected vote reporting.

Heading into election night, experts had been tracking whether the country could see a major generational shift in the electorate this year. So far, there aren't indications of that in the preliminary national exit polls.

The 18-29 year-olds and 30-44 year-olds make up the same percentage of the electorate as they did in 2016.

Those youngest voters are breaking toward Biden by much more than they did to Hillary Clinton in 2016, but among 30-44 year olds, Biden is only winning by about the same as Clinton. There are no major third-party candidates this year, while 10% of young people voted for a third-party candidate or gave no answer in exit polls.

Older voters, over 65, make up a similar percentage of the vote as they did in 2016, making up about 21% in preliminary exit polls compared to 20% in 2016.

There was concern that voting remotely for college kids who were not on campuses this year could be a factor, but after the protests this summer it is a surprising outcome.
