Democratic Sen. Bob Casey will seek a fourth term in office, bringing the power of incumbency and unmatched name recognition in Pennsylvania politics to his party’s defense of a seat in a critical presidential battleground state.
The announcement by Casey, the longest-serving Democratic U.S. senator in Pennsylvania history, gives Democrats a boost ahead of a difficult 2024 Senate map. They must defend incumbents not only in red states — Montana, Ohio and West Virginia — but also in multiple swing states.
