Much of the attention surrounding the 2018 election season focused on whether Democrats would be able to take control of the U.S. House and/or Senate, or whether one or both chambers would continue to have Republican majorities. Another important party battle was also underway, however, with Democrats attempting to cut into the historically high number of governorships–33–held by Republicans in 2018.

Democrats did not lack for opportunity: 36 states held gubernatorial elections in 2018, with 26 of the seats in question held by Republicans. While not all of the races were competitive, they were all important. In addition to determining policy priorities in the states and giving prominence to potential future presidential candidates, the gubernatorial election results will soon have a significant impact on another key political process: redistricting. Most of the governors elected in 2018 will lead their states in 2020, the year in which the important redistricting process will begin determining the shape of both Congressional seats and those in the state legislature.

In the end, Democrats picked up seven gubernatorial seats, while Republicans won one seat (in Alaska) formerly held by an independent. In 2019, as a result, Republicans will control 27 governorships while Democrats will control 23.

Below is a quick look at the 2018 races, including a look at which races featured open seats and the primary dates and results for each state.

While there is still time for incumbents not subject to term limits to change their minds, the lists below indicate the current open races and those with incumbent candidates. On the map, open races are indicated by a lighter shade of red or blue.
