East End native Carol Alvarado has been crusading for other people's municipal campaigns ever since she could walk, and last fall she finally won her own place on Houston City Council. The former aide to Mayor Lee Brown weathered an acrimonious contest against two opponents to win the District I seat without a runoff. This success came to her despite the fact that she was opposed by both her term-limited predecessor, John Castillo, and the other Hispanic member of council, Gabe Vasquez. The 35-year-old Alvarado won her race by utilizing a wealth of contacts built through more than a decade of community involvement. Somewhere down the road she might just face off with last year's Best Politician, Councilman Vasquez, for the right to become Houston's first Hispanic mayor.
