LOS ANGELES (AP) — Voters in Los Angeles gave a collective shrug Tuesday to the contest to replace Mayor Antonio Villaraigosa, turning out in small numbers after a low-profile campaign in which no issue or candidate galvanized the electorate.

Only about 22 percent of 660,000 mail-in ballots had been returned by Tuesday morning, and campaign strategists figured that when Election Day voters were added only about a quarter of the city’s 1.8 million voters would have cast ballots.
