From the KTRK story:
“Mario Gallegos was the first Mexican American elected to the Texas Senate from Harris County. He served two terms. Gallegos was a firefighter and a senior captain for 22 years. In 2007, he was elected “Governor for a day,” an honorary position awarded to the most senior senator who has not received the honor. In 2007, he announced he had cirrhosis of the liver. A few days later, he received a liver transplant.”
My friend and mentor, Babe Schwartz, visited Gallegos in the hospital shortly before he passed away. He told me that Gallegos was telling friends that he wanted Carol Alvarado to succeed him in the Senate. We offer our condolences to the Gallegos family.
