A blank Senate map lets anyone experiment with every conceivable party composition for the 2026 Congress.
Key points
- The NBC News "What If" map is an interactive sandbox for visualizing possible Senate seat distributions after the 2026 midterms.
- It starts with all seats unassigned, letting users assign each race to a party and instantly see the resulting majority scenario.
- The tool is not a forecast; it does not use polling or candidate data and should be viewed as an exploratory aid only.
NBC News has added an interactive "What If" feature to its Senate‑seats tracker, enabling readers to experiment with different configurations of party control after the 2026 midterm elections.
The interface presents a grid of Senate races, each initially marked as "Unassigned" with zero seats shown for Democrats or Republicans. Users can navigate the chart with arrow keys or a mouse, toggling each race between Democratic, Republican or unassigned status, and the tool instantly updates the overall seat count.
How the tool works
Designed as a scenario‑building exercise rather than a forecast, the tool lets visitors model outcomes ranging from a narrow majority for either party to a split or even a coalition‑style balance, depending on how they allocate the unassigned seats.
NBC News notes that the map does not incorporate real‑time polling, candidate filings or any official election data; it simply reflects the user's selections. Consequently, the visualizations should be treated as illustrative rather than predictive.
What users can explore
The feature also includes accessibility options: screen‑reader users can edit picks via a text list, and keyboard shortcuts allow navigation without a mouse. A brief instruction panel explains how to cycle through party assignments and exit the chart.
While the tool offers a hands‑on way to grasp the stakes of the upcoming Senate races, the outlet cautions that actual results will depend on a host of factors—candidate quality, campaign financing, voter turnout and unforeseen events—that the simulation cannot capture.
Reader questions
How do I assign a Senate seat to a party in the tool?
Click on a race or use the arrow keys to highlight it, then press Enter or Space to cycle through Democratic, Republican and unassigned options.
Does the map predict the actual election outcome?
No. The interface only reflects the selections you make and does not incorporate any real‑world polling or candidate information.
Is the tool accessible for screen‑reader users?
Yes. Users can edit seat assignments via a text list after the chart, and all navigation functions are keyboard‑compatible.
