A second statewide elected official has won reelection without opposition, with the departure Tuesday of former congressman Anh “Joseph” Cao from the attorney general’s race.

Cao filed paper’s this morning with the secretary of state’s office officially dropping out of the race in which he was challenging Attorney General Buddy Caldwell.

Caldwell and Cao are both Republicans.

Cao’s departure leaves Caldwell without any opposition.

State Treasurer John Kennedy already had no opposition in his reelection bid.

The open primary elections are scheduled for Oct. 22.
