Weight Transfer

Young and Hispanic voters moved furthest. The national balance moved mostly because white voters, men and people in their 30s and 40s moved, because there are more of them.

The national margin is a balance point. Put every group on a ruler at its margin, give each a weight equal to its share of voters, and the point where the ruler balances is the country's margin. That is the whole chart. Between 2024 and this week every weight slid left, and the balance point moved about 15 points, from R+2 to D+13.

Seen that way, the size of a swing and its effect come apart. Under-30s moved 33 points but carry a ninth of the weight, so they pushed the balance about 3.6 points. White voters moved 12 points, but at 73% of the electorate that pushed it nearly 9. Men moved the balance more than women (8.5 points against 6.9), and voters aged 30 to 44 more than any other age group.

  • Men went from about R+16 in 2024 to D+2: an 18-point move, the biggest of any large group.
  • Under-30s: D+8 to D+41. Hispanic voters: D+11 to D+40, undoing all of Trump's 2024 gain.
  • Black voters moved 10 points back, to about D+83. White voters moved 12, from R+16 to R+4.
  • 65-plus barely moved (6 points) and sits almost exactly on the national balance of 2024.
How swings are usually drawn, and what each one leaves out
Shift arrows on mapsThe wind maps newspapers draw by county. They show direction and size by place, but a near-empty county gets as long an arrow as a city.
Hairpins, dumbbells, arrow dot plotsGood for change by group. Every group looks equally heavy, so a group of 4% reads like one of 73%.
SlopegraphsClear for two moments and a few lines; tangled past six groups or three elections.
SwingometersThe BBC's dial, and the what-if simulators from Cook and FiveThirtyEight. One national number, or a hypothetical, not what happened.
Voter-flow diagramsThe Sankey charts of German and French election nights. They show who switched, but need panel data the US rarely has.
Ours: weight transferShows how far each group moved and how much that moved the country, on one ruler, with the national margin as the balance point. The arithmetic is exact: the balance is the share-weighted average.

The tipping scale

In shortA see-saw with its pivot at a tied vote. Each group is a weight: bigger groups weigh more, and groups sitting far from the middle press harder, the way a child at the end of a see-saw does. The beam tips toward the party the country chose; the amber diamond is where it would balance. Hover or tap a weight.

Margins are presidential for 2020 and 2024 and House for 2026, read from the reference chart to about a point. Weights hold the 2026 electorate fixed, so each beam's balance point is the share-weighted average of its groups (D+11 to D+13 in 2026, against about D+13 measured), and the coloured bar segments add up exactly to how far it moved. The tilt is drawn from each beam's turning force around Even (share × margin), capped at 6 degrees.

The ballot: who filled in the 15 points

In shortThe Democrats' gain since 2024, counted as filled bubbles. Each bubble is half a point of the national margin, and its colour is the group that filled it. A long row is a group that moved the country, not just one that moved a lot.

Each row is the group's swing since 2024 multiplied by its share of 2026 voters, in points of national margin, rounded to the nearest half point. Gender, race and age slice the same voters three ways, so each contest adds up to the whole swing on its own (15.4, 14.2 and 15.0 points; the gaps are rounding and changes in who turned out).
