SAN FRANCISCO, Nov. 5 (Xinhua) -- Incumbent San Francisco Mayor London Breed declared a victory for a full, four-year term in an easy mayoral race less than 90 minutes after the polls closed Tuesday evening.

Breed won 68.7 percent of votes in the race that lacked strong competition from any of the other five candidates, according to results of the real-time tally published by the San Francisco Chronicle website.

"I also want to take this opportunity to thank you for honoring me with four more years as mayor," she told a cheering crowd at her election party.

Breed became the first African-American female mayor of San Francisco in June 2018 when she won a special election to finish the remaining term of former Mayor Ed Lee in the wake of his sudden death in December 2017.

She was seeking her first four-year term in Tuesday's race and has vowed to give top priority to the city's homelessness crisis, pledging to add 1,000 new shelter beds for homeless people by 2020.
