Margaret Gómez, the longest-serving Travis County commissioner in history, is retiring early. She will continue her post overseeing Precinct 4 until June 11, when George Morales, who won the Democratic primary election for the seat last month, will be appointed to take over, Gómez said. Gómez, 81, said she is ready to step down after serving as a Travis County employee for nearly 53 years.
