San Antonio City Councilman John Courage is running for mayor. Courage made the announcement on Thursday afternoon in front of City Hall. Councilwoman Melissa Cabello Havrda has also said she plans to run for the office in next year's election, but Courage has filed paperwork to appoint a treasurer for his campaign. Mayor Ron Nirenberg is unable to run again because of term limits. At least three other City Council members are reportedly thinking of making a run for the open seat.
