Residents of Southeast LA County will vote on June 3rd to replace State Senator Ron Calderon. He's been indicted on federal corruption charges. But KPCC's Alice Walton says it's the latest in a string of public corruption cases in the Southland and investigated why that's happening.

Ron Calderon, D-Montebello, left, holds a brief news conference during first appearance at the Capitol since the FBI investigators raided his offices in Sacramento, Calif. Sen. Calderon was a no-show with an unexcused absence after at least a half-dozen FBI agents carted boxes from his Sacramento offices following a more than six-hour search in June 2013. Sen. Calderon did not answer any questions and no details have been given for the search and no charges have been filed. (AP Photo/Rich Pedroncelli, File)
