I don't really see this GOP platform winning though except in the Uber rural areas in all fairness to Texas. Places like Houston, San Antonio, Dallas, etc etc etc are all pretty fairly liberal compared to the rest of the state. The bigger cities would absolutely put the kibosh on it, not to mention anyone who thinks for more than five seconds and subscribes to "Separation of Church and State".
All the GOP wants a Christian led education, until it's revealed that education is Roman Catholic, and then people have simply gone too far!
