According to early voting totals, newcomer Alison Alter is beating her opponent, incumbent Council Member Sheri Gallo, in the Austin City Council District 10 runoff election with 65.64 percent of the vote, or 6,259 votes, according to the Travis County Clerk’s website.

According to early voting numbers, more than 9,500 votes, or 14.41 percent of eligible district voters, cast early votes between Dec. 1-9.

Among the four candidates who competed in the Nov. 8 general election, Gallo and Alter were the top two vote-getters. Gallo beat Alter by a 12-point margin, 48 percent to 36 percent. However, because neither candidate earned more than 50 percent of the popular vote, a runoff election was forced.

Gallo, who was elected to council in 2014, is seeking re-election for a full four-year term the Austin City Council. She was one of five council members to draw the short straw and receive only a two-year term when the council changed to 10-1 format in 2014.

Alter, who runs her own philanthropic advising company, Alter Advising, has been campaigning as the voice for the neighborhoods and the environment.
