Career
Radstaak ran for a seat in the 1967 Alberta general election as the Social Cr candidate in the new electoral district of Strathcona South. He faced a hotly contested race running against star Progressive Conservative candidate Oscar Kruger who played for the Edmonton Eskimos and two other candidates. Strathcona South was abolished in the 1971 boundary redistribution.
Radstaak ran for re-election in the new electoral district of Edmonton-Avonmore in the election held that year.
He was defeated by Progressive Conservative candidate Horst Schmid in a very closely contested race finishing second. Radstaak attempted to regain a seat to the assembly in the 1975 Alberta general election.
He faced Scmid for the second time but was defeated in a landslide finishing a very distant second.
