Sure, there are probably a handful of Texans (hi, RT!) who might object to the Govenor signing bills restricting abortion and outlawing gay marriage
in a church-run school, but doubtless they're just those "separation of church and state" weenies who don't understand the power of metaphor or of campaign contributions.
Besides, it's efficient: this way, after signing the bills, the Governor can wash in the Blood of the Lamb without even having to get in his car.
