Mr. Fong succeeds Mr. McCarthy nearly five months after he resigned from Congress, following his ouster from the speakership.
Mr. Fong will now serve until the term expires in January and will again face his Republican opponent — Mike Boudreaux, the longtime sheriff of Tulare County — in the fall to seek a full term.
Georgia, Idaho, Kentucky and Oregon also held primary contests on Tuesday, with presidential primaries in Kentucky and Oregon yielding notable protest votes against President Biden and former President Donald J. Trump.
Biden met significant resistance in the Kentucky primary, and a protest vote against him in Oregon faltered.
The protest vote against Mr. Biden there was nearly double that against Mr. Trump, who won about 85 percent of the vote in the Republican primary.
