Nearly a month after the November election, the Alameda County Registrar of Voters officially certified its results on Tuesday afternoon.

Fueled by a contentious presidential election, voter turnout in Alameda County topped 81 percent. The largely vote-by-mail election necessitated by the pandemic led to 75 percent of all registered voters in the county to vote from home.

The final results clinched a number of close races for candidates and ballot measures. Among them, former Alameda Mayor Trish Herrera Spencer is the winner of the second at-large seat on the Alameda City Council. She beat Amos White by 66 votes.

Two ballot measures at the county level were successful by the narrowest of margins. The countywide half-cent sales tax increase garnered 50.09 percent of the vote, according to the final results. It needed a simple majority for approval.

Measure X, a bond measure for the Alameda County Fire Department that was narrowly defeated in the March primary, required a two-thirds majority for passage last November. It passed with 66.78 percent.
