A city of San Diego sales tax hike could be trending toward voter approval, despite still trailing in the latest vote totals posted by election officials early Wednesday morning. Supporters believe Measure E — a one-cent sales tax increase that would generate about $400 million annually — is highly likely to surpass the simple majority it needs for approval once all the votes are counted.

Early election results Tuesday evening appear to have San Diegans rejecting a ballot measure intended to increase sales tax in the city to raise $400 million for city infrastructure needs — but the tally remains close.

Sales tax measures in San Diego and across the county were trailing on election night despite support from elected officials, including San Diego Mayor Todd Gloria.
