In a recent legal document, the State of Texas quotes the Supreme Court ruling in the Crawford case on the nationwide legality of requiring a photo ID in voting.  A 6-3 majority in Crawford case upheld the overall constitutionality of the Indiana photo ID law and the majority stated that the possible slight inconvenience to get a photo ID at an election office or drivers license office was no more significant or burdensome than the usual burdens of registration and voting.
