2026 midterm election map maker

What is on the ballot on 3 November 2026

Midterms are decided across several different geographies at once, which is why one map rarely tells the whole story.

Color by party, or shade by margin

For a results map, category mode is the one you want. Define a group per party, give each the color readers already expect, and assign states or counties to it. The legend builds itself from the group names, and changing a party color recolors every state in that group at once rather than making you re-click each one.

For a closer read, gradient mode shades by any number you have - margin, vote share, swing against 2022, or turnout. Logic rules cover banded presentations such as safe, likely, lean and toss-up, with a threshold per band.

County-level maps, where the swing actually shows

State maps call the race; county maps explain it. The full county map carries more than 3,000 counties, which is where national shifts become visible and where a statewide margin resolves into the places that produced it.

At that scale you will not want to click 3,000 shapes. Paste a two-column list of county names and values and gradient mode shades the whole map in one step.

Forecasts, scenarios and election night

Nothing ties the map to a real result, so the same tool handles a pre-election forecast, a what-if scenario, or live returns being filled in as they are called. Work autosaves as you go.

When you are ready, export a PNG for a post or a slide, an SVG for print, or paste an embed snippet so the map sits live inside an article.
