Vaus led by 1,245 votes Nov. 4 but his lead shrunk to 111 through Monday’s count.
Both candidates in the nonpartisan race are Republicans.
The district includes El Cajon, La Mesa, Lemon Grove, Poway and Santee and the San Diego communities of Allied Gardens, College Area, Del Cerro, Grantville, Navajo, Rolando and San Carlos.
It also includes East County’s unincorporated communities of Alpine, Campo, Julian, Ramona, Rancho San Diego and Spring Valley.
The winner will succeed Supervisor Dianne Jacob who was barred from running for re-election because of term limits. She was elected to the first of her seven terms in 1992.
