How the Associated Press determines election results

At The Christian Science Monitor, we rely on the Associated Press’ election results. This is how the AP determines the winners in more than 7,000 races.

First Look

In the 2020 United States general election, The Associated Press will declare winners in more than 7,000 races – starting with the White House and reaching down the ballot to every seat in every state legislature.

To do so, AP uses a 50-state network of stringers who collect votes at a local level, while other AP journalists gather results from state or county websites, as well as via electronic data feeds from states.

But how does the AP know when to call a race for a candidate? And more importantly, even, when not to call it? It’s a complex formula that involves looking at the number of votes counted, historical data, and AP VoteCast, a wide-ranging survey of the American electorate, among other things.

Accounting for early voters

News organizations have long relied on surveys of voters leaving polling sites on Election Day to gather data on how the country voted.

But this approach is no longer the best fit for an electorate that increasingly votes by mail and absentee methods, before polls even open on Election Day, says David Scott, a deputy managing editor who helps oversee AP’s coverage of elections.

Enter AP VoteCast, which debuted in 2018. Working with NORC at the University of Chicago, AP developed a new system designed specifically to account for the steady rise in votes cast before Election Day.

“This will be the first election in which more than half of voters cast their ballots in advance,” Mr. Scott said. “It’s why we took the time and spent the money to develop VoteCast.”

While the coronavirus pandemic has been an unexpected twist, Mr. Scott said AP VoteCast’s methodology is well suited for this moment. Research from AP VoteCast will show how many people voted early, among other things, helping AP’s race callers understand how the race is shaping up.

When the polls close

Not all races are closely contested. In some states, a party or candidate’s past history of consistent and convincing wins – by a wide margin – make a race eligible to be declared as soon as polls close. In these states, AP can use results from AP VoteCast to confirm a candidate has won, Mr. Scott said.

“The results from the poll – along with our analysis of early voting and other statistics – confirm our expectation that long-standing political trends in these states will hold,” Mr. Scott said.

Still, AP will not call the winner of a race before all the polls close in a jurisdiction.

How AP calls closely contested races

In closely contested races, there is no substitute for a detailed analysis of the vote count.

Race callers work with analysts who focus on statewide races, and together they study the incoming vote county by county.

In states where the information is available, they look at the ballots and see how many were cast in person on Election Day, or in advance by mail or in person. They also pay close attention to how many have been counted so far, and how many are left. Another important factor: The voting history of areas where votes are still being counted.

All of it is aimed at determining the answer to a single question: Can the trailing candidates catch-up with the leader? Only when the answer is an unquestionable “No” is the race is ready to be called.

When a race is ‘too close to call’

Beginning in 2019, AP’s Decision Desk started the practice of formally declaring some elections as “too close to call.” That happens when all outstanding ballots, save provisional and late-arriving absentee ballots, have been counted, and there is no clear winner.

AP may decide not to call a race if the margin between the top two candidates is less than 0.5 percentage points. On election night, AP generally won’t call winners in races for the U.S. House if the margin is less than 1,000 votes, and won’t call winners in races for state legislature seats if the margin is less than 2 percentage points or 100 votes.

In races where votes are still being tabulated, AP will not declare a race “too close to call” unless it is clear it will proceed to or be subject to a recount. That includes races where completing the vote count may take several days. In such cases, AP will describe a race as “too early to call” – an informal designation that indicates AP does not have enough data to make a race call.

What about recounts?

AP does not declare a winner of an election that will be – or is likely to become – subject to a mandatory recount.

In several states, recounts are mandated if the margin between the top two candidates falls below a certain level. AP will not call a race if the margin is in the recount range – or could end up in that range as final votes are counted.

In some states, recounts can be requested if the margin falls below a certain level. In others, candidates can request a recount regardless of the margin between the top two candidates. In such instances, AP will not call a race if the margin between the top two candidates is 0.5 percentage points or less, or if the margin could fall below that once all ballots are counted.

AP may call the race if the trailing candidate confirms he or she won’t seek a recount, or if the candidate publicly concedes the election.
