CNN reports on the floodgates opening on photo ID.  

Requests by Texas and Mississippi for clearance in their voter ID laws
were pending with the federal government when the high court struck down
the constitutionality of the act’s Section 4 on Tuesday, which also
appears to have nullified Section 5.  Delbert Hosemann, Mississippi’s secretary of state, interpreted the
court’s decision to mean his state was on “equal footing” with other
states and could move forward with its voter ID law without getting
permission from the government.

“The Court’s decision removes requirements for Mississippi to travel
through the expensive and time consuming federal application process for
any change to state, county, or municipal voting law,” he said in a
statement. “This chapter is closed.”

Hosemann said Mississippi would begin implementing its voter ID law starting Tuesday. Texas Attorney General Greg Abbott issued a similar statement,
declaring voting laws have been applied “unequally” to some states and
Tuesday’s ruling negates that inequality.
