ABC News -- Big (sort of) election day! You have a couple of governor races, some important referendums and a handful of mayoral races. Which brings us to the nations 4th biggest city of Houston where an openly gay woman is running for mayor. 52 year old city controller Annise Parker finds herself today in the midst of a very tight race (there will likely be a run-off). If she wins, shell be the first openly gay woman to be mayor of a major American city.
