Senate elections
The Institutional Revolutionary Party & the allied Green Party failed to gain a simple majority in either house. As a result, the PRI had to form crossparty coalitions in order to pass key reforms, particularly those requiring constitutional amendments.[4] In the July 2012 elections the PRI gained 2 seats, ending with 52. The PAN gained 5 seats, ending with 38. The PRD lost 1 seat, ending with 22. The PVEM gained 1 seat, ending with 9. The Labor Party lost 1 seat, ending with 4. The PANAL lost 3, ending with 2 seats. The MC lost 3 seats, ending with 1.[4]
