I think it's a photo ID--and then they must be on the rolls, of course.

Well, that's something....
The TX Sec'y. of State also told me that photo ID is required in lieu of Voters Reg., but as a practical matter, it does not appear to be enforced -- particularly in dem. precincts (no surprise). That lack of enforcement leaves the process wide open to fraud.
