If the polls just closed, how can AP already declare a winner?

WASHINGTON (AP) — Control of the White House and the narrowly divided Senate and House may hang in the balance on Nov. 5, but don’t expect election night to be all nail-biters and barn burners. Chances are some winners will be declared before a single vote has been tallied, just as the polls close in those states.

So what gives?

Although determining a winner before any votes have been counted may seem counterintuitive, race calls at poll closing time in uncontested or landslide races have been a routine part of election nights for decades, even though competitive, hotly contested races that can take hours, days or even weeks to decide tend to be the most memorable and attract the most attention.

The Associated Press will consider multiple factors and analyze available data before determining whether a winner can be declared when polls close in a given state. But the AP will never declare the outcome in a competitive contest before enough votes are counted to make the winner clear.

Uncontested races

Many of the races called just as the polls close are uncontested elections where only one candidate appears on the ballot and is therefore the only possible winner of the race. Voters in some parts of the country live in multimember districts for offices such as state legislature, where more than one candidate is elected in a district. In those districts, an uncontested race is one where the number of candidates on the ballot is equal to or less than the number of seats available in that district.
