San Antonio state Rep. Mike Villarreal said on Sunday that he would not serve his new term in the Legislature in order to run full time for mayor of his hometown. The announcement set off a flurry of activity among Alamo City politicos. State Sen. Leticia Van de Putte said that she was considering a run for mayor, and state Rep. Trey Martinez Fischer said he would be interested in running for Van de Putte's Senate seat should she run for a different office.
