The victorious candidate in this election was José Natividad González Parás, representing an alliance of the Institutional Revolutionary Party (PRI) and the Green Ecological Party (PVEM).
Legislative power in the state rests in a unicameral legislature composed of 42 deputies, also elected via secret ballot by the citizenry, 26 of whom are directly elected and 16 chosen according to a plurinominal system involving proportional representation.
Following the election, the 70th Legislature consists of 23 PRI deputies, 11 from PAN, 3 from PT, 3 from PVEM, 1 from PRD, and one independent.
