Groups on both sides of the Pre-K 4 SA measure are engaging in competing messages as early voting continues, and from the steps of City Hall on Monday, the San Antonio Family Association, along with members of the Tea Party and South Texas Alliance for Progress, shouted that Mayor Julián Castro's measure just won't work.

One member likened the program to a car buyer not being able to test drive the vehicle or look under the hood before purchasing.
