Republicans control the Senate 53-47. Here is the math for 2026, using official counts and the Cook Political Report’s ratings; Jamoke News makes no predictions.

What each side needs

A majority is 51 seats. In a 50-50 Senate the vice president, currently Republican JD Vance, breaks ties, so Republicans keep control at 50 seats and Democrats need 51: a net gain of four seats.

Seats on the ballot

• 35 seats: 33 regular (Class 2) seats plus special elections in Ohio (JD Vance’s former seat) and Florida (Marco Rubio’s former seat).
• Republicans are defending 22 of them and Democrats 13.
• 11 senators are retiring (7 Republicans, 4 Democrats), the most in one cycle since 1996.
• Two Republican senators lost renomination: Bill Cassidy of Louisiana and John Cornyn of Texas.
