In 2004, Oller ran for Congress in
California's 3rd congressional district, but narrowly lost the Republican primary to former California Attorney General
Dan Lungren. On January 10, 2008, Oller again ran for Congress, this time in
California's 4th congressional district, for a seat being vacated by retiring Congressman
John Doolittle. In a statement, Oller said his decision was "a bitter pill indeed for me to swallow." But, he said he was endorsing McClintock to prevent the election of Ose, whom he labeled as "an unarguably liberal Republican." Oller ran for the newly former 5th Assembly District in 2012, facing
Madera County Supervisor
Frank Bigelow in the November general election. ==Legislative record==
