Wyman was vice president of the Antelope Valley Board of Trade in 1976 when he first ran for California State Assembly from the Tehachapi-Palmdale based 34th District.

He narrowly lost to Democratic incumbent Larry Chimbole but went on to defeat him two years later and served in the Assembly from 1978 until 1992,[2] when he opted not to seek reelection and instead run for congress.

He moved to a small apartment in Phelan, California (in the rural San Bernardino County desert) to qualify to run, which caused his political opponents to accuse him of being a carpetbagger.

The 25th Congressional district was created after the 1991 reapportionment and was centered on the new city of Santa Clarita in fast growing northern Los Angeles County.

Wyman bounced back less than a year later when he won a special election for the Fresno-based 16th state Senate district in 1993.

[5] In 1996 he ran for a neighboring state Senate seat and lost the GOP primary again, this time to Palmdale area Assemblyman Pete Knight.
