David Francis Cargo (January 13, 1929 – July 5, 2013) was an American attorney and politician who served as the 22nd governor of New Mexico between 1967 and 1971.

[1] He remains one of the youngest governors elected to date in U.S. history, along with Harold Stassen in Minnesota (1938), Bill Clinton in Arkansas (1978), Christopher "Kit" Bond and Matt Blunt in Missouri (1972) and (2004), respectively, and Bobby Jindal in Louisiana (2007).

[citation needed] Cargo ran for Governor in 1966, facing Clifford J. Hawley of Santa Fe in the Republican primary.

"[6] On May 8, 1970, Cargo sent National Guard troops to the UNM campus when Jane Fonda spoke to an estimated 700 protesters.

A jury in Albuquerque eventually sided with Cargo, the National Guard, and the other politicians involved leaving victims to pay their own medical bills.

[12] Cargo ran unsuccessfully for New Mexico's other Senate seat in 1972 but again lost the primary, this time to the eventual winner, Pete Domenici.

[11] He tried for a gubernatorial comeback in 1994 but finished in fourth place with 13 percent in the primary and lost to the eventual winner, Gary Johnson.
