The Democratic Party of New Mexico (DPNM) is the affiliate of the Democratic Party in the U.S. state of New Mexico. It is headquartered in Albuquerque and led by Chair Jessica Velasquez, Vice Chair Manny Crespin, Secretary Pamelya Herndon, and Treasurer Rayellen Smith. It is currently the dominant party in the state, controlling all of New Mexico's three U.S. House seats, both U.S. Senate seats, both houses of the state legislature, and the governorship. It is the primary opposition to the Republican Party of New Mexico. The party has provided 19 of the 31 governors of New Mexico, including three since the 1990s (Bruce King, Bill Richardson, and Michelle Lujan Grisham). Other key Democratic figures in New Mexico's history include David Meriwether, Henry Connelly, Ezequiel Cabeza De Baca, Clyde Tingley, Jerry Apodaca, and Toney Anaya. The New Mexico Democratic Party is led by Jessica Velasquez, with other modern prominent figures include modern governor Michelle Lujan Grisham, Raúl Torrez, Howie Morales, Maggie Toulouse Oliver, Mimi Stewart, Brian Egolf, and Tim Keller. Historical development New Mexico Territory elected its first delegate to the U.S. House of Representatives in 1850: Richard Hanson Weightman, a Democrat. At this time, the Democratic Party was socially conservative and many Democrats supported expanding slavery into new Western territories. This pro-slavery position stopped New Mexico's first attempt at a state constitution (which prohibited slavery) from being ratified in 1850, preventing the territory from becoming a state. In the early 1900s, Democratic politician Octaviano Ambrosio Larrazolo led a movement in favor of civil rights for Hispanic and Latino Americans and Spanish speakers in New Mexico. He found that most Latinos identified as Republicans, which disturbed Larrazolo because he felt that the Republican political machine in the territory was exploiting its Hispanic voters. When New Mexico Territory was preparing to become a state in 1910, Larrazolo was selected as a delegate to the constitutional convention. He succeeded in making sure that the state's constitution protected and guaranteed the political, civil, and religious rights of those of Spanish and Mexican descent. However, other state Democrats opposed these protections and unsuccessfully attempted to prevent the new constitution from being ratified. After being opposed by his own party, Larrazolo became a Republican and served as a Republican governor and senator from New Mexico. Like the national Democratic Party, the Democratic Party of New Mexico underwent significant ideological changes throughout the 20th century. Since
