Readers can choose winners to see the House and Senate split

The Journal’s forecast methodology uses three labels. “Likely” is defined as “Not competitive but could become competitive.” “Lean” is defined as “Competitive, one party has an advantage.” “Tossup” is defined as “Most competitive, either party has a good chance.”

The Wall Street Journal describes its race forecasts as aggregates based on ratings from three nonpartisan political analysts: the Cook Political Report with Amy Walter; Inside Elections with Nathan L. Gonzales; and Larry Sabato’s Crystal Ball at the University of Virginia Center for Politics.

The accompanying interactive asks readers to predict which party will win each competitive race. Clicking a race lets the reader choose a party, and the graphic then shows the overall chamber split based on those decisions.

Republicans begin with a 53-47 majority in the Senate. There are 35 Senate seats up for election, and most are held by Republicans. To retain control, Republicans need to reach 50 seats and can count on Vice President JD Vance to break any ties; Democrats need 51 seats to take back the chamber.

The House begins with a 219-seat Republican majority against 214 seats held by Democrats, including independent Kevin Kiley, who caucuses with Republicans. The current-composition listing adds 2 vacant seats. Since the 2024 election, 10 states have redrawn maps between censuses to favor one party over the other.

Against that methodological and numerical background, control of the House and Senate was on the line on Election Day. Election watchers rated Democrats as having a strong chance of taking back the House from Republicans’ razor-thin majority. The GOP-controlled Senate was also in play: Democrats were taking aim at a broader-than-expected battlefield while also trying to fend off Republicans’ effort to flip blue seats.
