The U.S. election night will not be decided only at the ballot box. While authorities count millions of ballots, the leading U.S. media outlets will use statistical tools capable of anticipating which party is moving toward control of Congress, even when numerous votes are still left to be counted.
The Needle, from The New York Times; Futurecast, from CBS; and Magic Wall, from CNN, will play a part in the coverage of this year’s midterm elections on November 3, in which the entire House of Representatives is renewed and approximately one third of the Senate.
These systems make it possible to visualize provisional results, identify changes in voting behavior, and estimate how the remaining races might evolve. However, their forecasts do not amount to official results and may be adjusted as the counting progresses.
The Needle: The New York Times’ election needle
The New York newspaper brings back The Needle, one of its best-known tools for interpreting election results.
Its operation combines data provided by Associated Press with information coming from polling places across the country. To compile this latter information, the newspaper will use more than a hundred automated data-extraction systems published by authorities.
The tool analyzes counted votes and compares them with each territory’s electoral patterns to estimate how the races may evolve.
Its main feature is that it does not limit itself to showing who is leading the count, but instead provides a statistical estimate that changes as new results come in.
This allows a candidacy to appear better positioned in the projection even if it still does not lead the provisional count, if the models estimate that the votes yet to be counted could favor it.
Futurecast: CBS launches an indicator to track control of the two chambers
CBS News incorporates tonight Futurecast, a tool designed to display in real time which party is moving toward control of the House of Representatives and the Senate.
The system uses statistical models developed by the network and presents its estimates by means of an election needle.
Unlike traditional charts, which exclusively show the number of seats assigned to each party, Futurecast aims to provide an overall reading of the parliamentary balance as results become known.
The network will complement this tool with a specialized broadcast, The Nerd Show, hosted by Anthony Salvanto and Caitlin Huey-Burns, dedicated to the analysis of data and electoral trends.
CNN renews Magic Wall and presents Sightline
CNN has also reinforced its technological deployment for these elections.
The U.S. network has updated Magic Wall, the interactive map that John King uses to examine results by states, counties, and districts.
The digital version allows users to view detailed territorial information and, in certain modes, compare results with previous elections.
To this tool is added Sightline, a new system that analyzes the chances of each candidacy based on the data it receives from CNN’s election team.
Its methodology takes into account the source of the votes, their comparison with previous elections, the statistical confidence of the estimates, and the volume of votes still outstanding.
The intention is to explain not only who is pulling ahead, but also what information is missing to determine whether an electoral advantage can be considered sufficiently solid.
Why media outlets can announce winners before the official count
The main U.S. networks have specialized teams, known as Decision Desks, that analyze provisional results and determine when they can project a win.
To do so, they combine real data, electoral history, polling, and statistical models.
Associated Press plays a fundamental role in this process, as it compiles results from thousands of jurisdictions and provides electoral information used by numerous media outlets.
However, each network can apply its own criteria before announcing a winner.
The difference between a projection and an official result is especially important in the closest elections, where the count can be extended for days and outstanding votes can alter early leads.
New tools make it possible to follow that evolution practically in real time, although final certification is exclusively the responsibility of election authorities.
