Between 1967 and 1975, Mathias served four terms in the United States House of Representatives as a
Republican, representing the northern
San Joaquin Valley of California. Mathias was re-elected three times without serious difficulty, but in 1974, his Congressional district was significantly redrawn in a mid-decade state redistricting plan. Renumbered as the 17th, Mathias's district acquired a large section of
Fresno while losing several rural areas. Mathias was narrowly defeated for re-election by
John Hans Krebs, a member of the
Fresno County Board of Supervisors. Mathias was one of several Republicans swept out of office in the wake of the
Watergate scandal. From June to August 1975, Mathias served as the deputy director of the
Selective Service. Mathias was also a regional director in the unsuccessful 1976 presidential election campaign of
Gerald Ford. ==Death==
