Early projection, based on early and incomplete polling: the likely matchups, each weighted by the betting markets' odds of both nominations, not a result. Each county is its 2024 presidential margin moved by its state's projected swing; set a national vote and every state, district and county moves by the same amount from our projection.

About the 1866 governor elections
The 1866 elections were a referendum on Andrew Johnson's handling of Reconstruction. Johnson opposed the Fourteenth Amendment and campaigned against Radical Republicans in his "Swing Around the Circle" tour, which went badly. Northern voters sided with Congress, and Republicans won 12 of the 14 governorships on the ballot, with Democrats taking only two. Some contests were tight. Joseph R. Hawley won Connecticut by less than a point over James E. English, and George L. Woods held Oregon by about 1.4 points. In Pennsylvania, former Union general John White Geary beat Heister Clymer by about 3 points in a race fought largely over Reconstruction and Black suffrage. Delaware stayed Democratic with Gove Saulsbury. Elsewhere the Republican margins were comfortable. Joshua L. Chamberlain, the hero of Little Round Top, won Maine by about 25 points over Eben F. Pillsbury, and Michigan, West Virginia and Nevada also returned Republican governors. The results gave Radical Republicans the strength to pass the Reconstruction Acts of 1867 over Johnson's veto.

Margin: the Democrat's share of all votes minus the Republican's. Margins are Democrat minus Republican, of all votes. Certified results, from the states' own archives, the MIT Election Data and Science Lab, Heideman (2026) and Algara & Amlani (2021). By county: "As they were" draws each county as it stood on election day; "Today's" shares the old votes among today's counties by area, so its county detail is an estimate.
