I don’t have live tool access in this turn to pull the latest list, but I can outline how to identify which governors were up for reelection in 2020 and provide the general picture from that cycle. Direct answer (based on the 2020 cycle):
- In 2020, 11 gubernatorial races were on the ballot nationwide. Of those, 9 incumbents sought reelection and all 9 incumbents won re-election. The two open-seat contests were in Montana and Utah; Montana flipped to Republican Greg Gianforte, while Utah re-elected a Republican to the open-seat race.
- In practical terms, the following incumbents were on the ballot and won:
- Delaware: John Carney (D)
- Indiana: Eric Holcomb (R)
- North Dakota: Doug Burgum (R)
- Washington: Jay Inslee (D) (seeking a third term)
- Additionally, several other states had incumbents running who successfully secured another term.
- The only party change in 2020 was Montana, where the governorship switched from Democrat to Republican.
If you’d like, I can pull the exact list of all 11 races and indicate for each whether the incumbent ran and whether they won, once I have access to current browsing tools. I can also provide a state-by-state table showing incumbents, challengers, and outcomes.
