SAN DIEGO (Reuters) - A Democrat seeking to become San Diego's first Hispanic mayor was trailing his Republican rival on Tuesday in their race to succeed ex-Mayor Bob Filner, who resigned amid a hail of sexual misconduct allegations, early election results showed.
Voters in California's second-most populous city appeared headed for a return to Republican leadership as City Councilman Kevin Faulconer opened a lead of nearly 10 percentage points against Democrat David Alvarez, with ballots from 63 percent of precincts counted.
Public opinion polls going into the Tuesday's election showed the race was too close to call, giving Faulconer, backed by the city's downtown establishment, a razor-thin edge and showing 7 percent of voters still undecided.
The winner will succeed the disgraced former mayor who resigned at the end of August after a string of women, starting with his then-press secretary Irene McCormack Jackson, came forward with allegations of sexual harassment.
