Does the State of Texas have a Problem with the Separation of Church and State?

Public debates about the proper extent of church/state separation in the U.S. remain vigorous and impassioned. Politically active evangelical Christians such as David Barton, a former co-chair of the Texas Republican party, emphasize the religiosity of the nation's founders and assert that "separation of church and state," as widely understood by modern historians and jurists, is a "myth" and that the U.S. was founded as a religious, Christian nation. Or is this a Conservative problem.
