California Rep. Susan A. Davis announced Wednesday that she is not running for reelection, opening up a safe Democratic seat in San Diego.

Davis, who was first elected in 2000, is the third House Democrat to retire so far this cycle.

“My decision today represents a desire to live and work ‘at home’ in San Diego,” the 10-term congresswoman wrote in a letter to her constituents. “I will continue to give my all for the next sixteen months and will work as earnestly and as enthusiastically as I have always tried to do.”

Hillary Clinton carried the 53rd District by 35 points in 2016, while Davis won reelection last year by 38 points. Inside Elections with Nathan L. Gonzales rates the 53rd District race Solid Democratic.
