In the four states that held elections – Louisiana, Mississippi, New Jersey, and Virginia – 19 Republican incumbents (10 in primaries and nine in general elections) lost re-election, followed by eight Democrats (six in primaries and two in general elections), and two independent or minor party incumbents (both in general elections). 

These totals include data from both legislative chambers in the four states. Mississippi, New Jersey, and Virginia held elections on Nov. 7, 2023, while Louisiana held its election on Nov. 18.
