In the lead-up to the election, two prominent electoral alliances were formed: the ruling coaltiton Juntos Hacemos Historia, a left-wing coalition consisting of MORENA, the Labor Party and the Ecologist Green Party of Mexico, and Va por México, a big-tent featuring the National Action Party, the Institutional Revolutionary Party and the Party of the Democratic Revolution. Additionally, Citizens' Movement participated in the elections as an independent party. 13 of the 15 gubernatorial seats up for election were being defended by a party in Va por México.
