As America gears up for significant electoral decisions, questions loom regarding pivotal races such as whether Zohran Mamdani will succeed in securing the mayor's office in New York City, who the next governor of New Jersey will be, and whether California will implement a new congressional map. These questions are set to be addressed as the Associated Press (AP) tabulates ballots and announces winners across hundreds of local races on election day this Tuesday.

The AP has served as the go-to source for election result reporting for nearly 180 years, providing a vital service in the absence of a nationwide body to compile and release these results. Given that elections are managed locally by countless offices and many states lack direct tracking for results, AP fills this gap by ensuring that data is collected efficiently and presented uniformly.

Vote count reporters are dispatched to work directly with local election officials, gathering results in real-time and submitting them as they are made available. The AP can make up to 21,000 updates an hour during busy general elections as they continuously compile the latest tallies.

To accurately determine winners, the AP analyzes not just the current tallies but also the volume of uncounted ballots, where they originated, and the methods by which they were cast, as voting trends have shown varying patterns across different demographics. This analytical approach aids in predicting how leads may shift as ballots are counted over time.

In the fast-paced environment of election night, races can often be called before all ballots are counted when a clear winner is projected. The AP's race calls are not merely predictions but are grounded in thorough assessments of the data at hand, allowing them to provide reliable updates as races unfold.
