Alison Alter leads incumbent Sheri Gallo and Rob Walker in political donations so far this election season, according to the latest round of campaign finance reports due to election officials Tuesday. The Austin City Clerk's office does not show a report from candidate Nicholas Virden.

Every opposed candidate in the Nov. 8 election must file a contributions and expenditures report 30 days before the election. This latest round of reports, the first mandated disclosure since this summer, covers all financials from July 1 to Sept. 29, according to the Texas Ethics Commission.
