Moderate Democratic Senator Tom Carper to Retire After Decades in Office

Sen. Tom Carper announced he will not run for reelection in 2024 after more than 20 years in the Senate.
Carper has served as a Democratic senator from Delaware since 2001 and previously served as governor.
Carper's decision opens up a competitive Democratic primary to succeed him in the reliably blue state.
Carper endorsed Rep. Lisa Blunt Rochester to replace him, and she would be the first Black woman senator from Delaware if elected.
Carper is the fourth Senate Democrat so far to announce retirement, complicating the party's hopes of keeping the Senate majority.
