Data: How much money San Antonio mayoral, city council candidates have raised and spent for May 1 election Incumbents hold fundraising edge over opponents, reports show Published: Updated: Tags: . (Henry Keller/KSAT) SAN ANTONIO – With less than a month before the May 1 election, a KSAT analysis of campaign finance records shows that the incumbents running for reelection, including the mayor and San Antonio’s City Council members, have more funds at their disposal than their challengers. With several crowded races on the ballot — more than 80 candidates are running for 11 seats — and hundreds of thousands of dollars in contributions and expenditures, some of the races might be too close to call on election night and could be headed to overtime in the form of a runoff election.
