Because Cranley is term limited as mayor, he has been mentioned as a possible Democratic candidate for governor of Ohio in 2022. In February 2020, Cranley became the first candidate to announce and explore a possible run for governor in 2022 against Republican incumbent Mike DeWine.^[17] He officially entered the race for the 2022 Democratic nomination for governor on August 10, 2021.^[18]

In his campaign, he criticized the Ohio Republican Party for rigging elections through gerrymandering and for corrupt legislation like HB6, which led to the Ohio nuclear bribery scandal.^[19]
