Haldiman married Blanche Elizabeth Birdno of Safford, Arizona on April 15, 1917.

He finished first of three candidates in the Democrat primary, and was the top vote-getter in the November general election.

There was a five-man race in the Democrat primary, and initially he was declared one of the two winners, along with Frank T.

After the votes were counted a second time, it was found that Haldiman had actually finished third, so he was not one of the two Democrat nominees.

[14][15] In the general election, Haldiman and his fellow Democrat, Marvin E. Smith, faced off against a single Republican opponent, Richard H. Schellschmidt.

[19][20] He went up against incumbent Republican Howard Pyle, who easily defeated him in the general election 156,592 to 103,693.
