LGBT participation is a part of the long-governing Institutional Revolutionary Party (PRI). Since the triumph of the Liberals under President Benito Juárez in the 1860s and the 1910 Revolution, there has been separation of church and state in Mexico. With morality generally considered the province of the Church, the PRI (which considers itself the party of the Revolution) has generally been reluctant to be seen as implementing the will of the Catholic Church. However, it has also been careful not to offend Catholic moral sensibilities. Nevertheless, most individual officeholders tend to view LGBT issues as a private matter (to be ignored) or a moral problem (to be opposed). The PRI has allied with the PAN to block legislation concerning LGBT rights in some states (except in some cases). The party unanimously voted in favor of the recognition of same-sex civil unions in Mexico City and Coahuila, for instance. There was some internal debate within the PRI whether or not the party should have a platform plank on the issue.
