in the simultaneously-held senate election and fared better in Orange County than she did in 1998, Republican Bill Jones defeated her in the county, 51% to 43%. While the 39% that John Kerry received is higher than the percentage Bill Clinton won in 1992 or 1996, the percentage of the vote George W. Bush received in 2004 is the highest any presidential candidate has received since 1988, showing a still-dominant GOP presence in the county. In 2006, Senator Dianne Feinstein won 45% of the vote in the county, the best showing of a Democrat in a Senate race in over four decades, but Orange was nevertheless the only Coastal California county to vote for her Republican opponent, Dick Mountjoy. The county is featured prominently in Lisa McGirr's book Suburban Warriors: The Origins of the New American Right. She argues that its conservative political orientation in the 20th century owed much to its settlement by farmers from the Great Plains, who reacted strongly to communist sympathies, the civil rights movement, and the turmoil of the 1960s in nearby Los Angeles — across the "Orange Curtain".

Republican Assemblyman Van Tran was the first Vietnamese-American elected to a state legislature and joined with Texan Hubert Vo as the highest-ranking elected Vietnamese-American in the United States until the 2008 election of Joseph Cao in Louisiana's 2nd congressional district. In the 2007 special election for the vacant county supervisor seat following Democrat Lou Correa's election to the state senate, two Vietnamese-American Republican candidates topped the list of 10 candidates, separated from each other by only seven votes, making the Orange County Board of Supervisors entirely Republican; Correa is first of only two Democrats to have served on the Board since 1987 and only the fifth since 1963.
