Politics & public opinion
Follow changing answers, compare question wording, and uncover differences that a national average hides.
US adults · Nationscape weekly survey, 2019–2021
Sympathy broke the week of the murder
Did racial sympathy really jump when George Floyd was killed, or would a break appear wherever the cut was placed?
Hides: What caused the break. The model dates it to the week but cannot separate the video, the protests and elite cues.
Try it: Drag the cut to any week
2,839 US counties · Stanford DIME donors and 2020 presidential returns
Where the money and the vote disagree
Which counties vote one way while their reliable donors lean the other — and who lives there?
Hides: Individuals. A county’s donor average says nothing about any one resident, and the national donor pool leans left.
Try it: Select counties on the scatter
US federal donors · Stanford DIME, 1980–2024
The donor centre emptied first
Where do reliable campaign donors sit on the left–right scale in each election cycle, and did the middle empty out?
Hides: Donors changing their minds. Each donor’s score is fixed; the ridges show who was giving each cycle.
Try it: Switch donor weighting
US voters · General Social Survey and ANES, 1948–2024
The outlier depends on the axis
Which slice of the electorate stands furthest from everyone else — and does the answer change between economic and social questions?
Hides: Design-based uncertainty. The intervals are bootstrap estimates, and the GSS moved online in 2021.

US voters · Cooperative Election Study, 2008–2024
Outnumbered, and defecting
How much more often do partisans vote for the other party when their county leans against them — and how many people live where that effect is steepest?
Hides: The thin ends. The most extreme rates come from the smallest groups of respondents.
Try it: Switch the axis
US counties · presidential returns, 1976–2024
Counties sorted into landslides
Between 1976 and 2024, did counties drift apart gradually or sort into landslides — and how far did the county map part from the national vote?
Hides: Population. Every county counts once, so the ridges describe the map rather than the vote.
Try it: Thirteen elections
Eleven former Confederate states · county presidential returns, 1872, 1900, 2024
The map remembers, upside down
Does the South’s 1872 county map still predict how its counties vote?
Hides: Who could vote. Jim Crow–era Democratic shares describe a largely whites-only electorate.
Try it: Point at a county
US voters · Cooperative Election Study, presidential years 2008–2024
The cost of living outnumbered
Does the extra defection among a party’s local minority hold up election after election?
Hides: Cause. Who moves where, and why, feeds the gap too.
Try it: Hover to read each election
3,099 US counties · Stanford DIME donations and adult population
A sliver of the country funds the rest
What share of American adults supply half of all individual campaign donations?
Hides: Individual donors. Counties are the unit, so a curve over people would be steeper still.
Try it: Drag along the curve
US partisans · American National Election Studies, 1978–2024
The cold mass at zero
How warmly do partisans feel about the other party, and how many now give it a literal zero?
Hides: How much is survey mode. Recent waves were mostly online, and online answers give more zeros.
Try it: Eight survey waves
