Update: November 2, 2024: Nevada Senate is re-added because it polls have tightened and the per-vote leverage is high. It is exceeded only by Nebraska.

This ActBlue is for optimized donations for control of U.S. Senate, U.S. House, and critical state legislative chambers and ballot questions. This list will be updated regularly.

At stake in 2024 are control of the U.S. Senate and House, as well as key state legislatures. Your donations have the greatest effect when they are directed at close races where swinging a few votes might have a major effect on the political landscape.

To retain control of the U.S. Senate, Democrats must win five of the seven races that are currently within 6 points in either direction: Arizona, Florida, Montana, Nebraska, Ohio, Pennsylvania, and Wisconsin. Montana and Nebraska have the Senate races with per-voter power greater than 20 out of a maximum 100, as defined at the Princeton Election Consortium. Nebraska has unusually high leverage because of its close margin and small population, and is underfunded compared with Montana.

The U.S. House has close to 50 competitive races. Rather than list them all, the focus is on races where there is also a key statewide race.

In the U.S. House, Nebraska's Second Congressional District will matter for House control. Voters there also can vote in the U.S. Senate election, which is currently on a knife edge. Tony Vargas seeks to unseat Don Bacon. Voters in Pennsylvania's Eighth Congressional District can vote for incumbent Matt Cartwright, as well as in pivotal Presidential and Senate elections.

At the level of state legislatures, two states are on the edge of a legislative majority and are also important for the Presidency: Arizona and Pennsylvania. Arizona is particularly attractive because of the combination of Presidential, Senate, and three competitive House races, as well as an abortion rights initiative. Selected here is Arizona state Senate District 17. The candidate there, John McLean, is an aerospace engineer running for an open seat. That district also overlaps with Arizona Congressional District 6, a swing U.S. House district where Kirsten Engel is running.

Reproductive rights are on the ballot in ten states. The one state where it is on the edge of passing is Florida: Amendment 4 requires a 60% vote to pass, and support is likely to be near that threshold. Floridians for Freedom sponsors that amendment.
