Born in
Wausau, Wisconsin, Belter graduated from high school in
Wautoma, Wisconsin. He then received his bachelor's degree from
University of Wisconsin and his law degree from
University of Wisconsin Law School. He practiced law in Wautoma, Wisconsin. He was a real estate broker and a bank director and then president. Belter was a justice of the peace and was district attorney for
Waushara County, Wisconsin from 1968 to 1977. He was also the attorney for
Ed Gein during his 1968 trial in Waushara County for the murder of Bernice Worden. (Judge Robert H Gollmar 1968). Belter also served in the Wisconsin State Assembly as a
Republican from 1953 to 1957, after unsuccessfully seeking the Republican nomination for Assembly in that district in 1948 and 1950. He was defeated in the 1956 Republican assembly primary. In 1982, when it seemed no other Republican was willing to challenge incumbent
Bronson La Follette, the party attempted to recruit Belter to run for
Wisconsin Attorney General. He consented to the run, but the Party ultimately did not collect enough
signatures to put his name on the ballot, and he received a small number of write-in votes in the election. ==Electoral history==
