[11][12][13][14] The party's 1978 state convention was attended by Washington Post columnist Nicholas von Hoffman and former Republican representative Sam Steiger who addressed them on political fundraising.

[16] The national party's presidential candidate, Ed Clark, attended the party's 1979 and 1980 state conventions and offered support to their attempts to regain ballot access and to place a ballot measure to eliminate taxes placed on food or food products and to repeal Arizona's auto-emissions tests.

[20][21][22] At their 1982 state convention Ed Clark addressed them for the third time, but announced that he would not seek the party's 1984 presidential nomination as to prevent it from becoming a cult of personality.

[29] In 1986, Ken Sturzenacker, the chairman of the party, resigned after the executive committee ousted him from his post after he was accused of spending money without authorization and for failing to collect enough signatures to gain ballot access for the 1986 elections.

[34] The party appealed the decision to a superior court which ruled in their favor allowing their city council candidate to run.

[61] In 2022, the Libertarian party nominated Marc Victor (who had been their nominee in 2012 against Jeff Flake) in the 2022 United States Senate election in Arizona.
