When We Might Know Election Results

Six Senate races were uncalled in five states: Alaska, Georgia, Maine, Michigan and North Carolina.

Georgia has two races, both involving Republican incumbents whom Democrats hope to unseat. One, between Senator David Perdue and Jon Ossoff, might be decided in the next few days or might go to a runoff in January, depending on whether a Libertarian candidate gets enough votes to keep both major-party candidates below 50 percent. The other race will require a runoff between the incumbent, Kelly Loeffler, and Raphael Warnock, a Democrat.

When will we know the results?

This will probably vary significantly from state to state. Let’s take them one at a time.

Alaska

Alaska may well be the last state to be called, because officials there won’t even begin counting mail ballots, or early in-person ballots cast after Oct. 29, for another week. That being said, it’s a red state and isn’t really competitive. Mr. Trump will probably win here pretty easily, and Senator Dan Sullivan, a Republican, probably will too.

Arizona

Arizona may be called soon. Mr. Biden is leading by five percentage points with more than 80 percent of the estimated vote counted, and some news outlets, including The Associated Press and Fox News, have already called it for him. The New York Times and others have not done so, but Arizona officials expect to finish counting ballots on Wednesday, so we shouldn’t be waiting too long for an answer.

Georgia

Georgia might have been called already if not for a burst pipe at a site in Fulton County where election officials were counting absentee ballots, which delayed the counting process in and around Atlanta.

Mr. Trump was ahead in the state by a little over two percentage points with 92 percent of the estimated vote counted, but the uncounted votes from such a heavily Democratic area could close the gap, and the secretary of state’s office cautioned against relying on the current results given that fact.
