CBS – DFW reports that unless a federal judge intervenes, the South Texas city of Edinburg could be the first to enforce a new voter ID law next week, and lawyers will likely use the special election to gather evidence to strengthen lawsuits to block it in the future. While the U.S. Justice Department and several civil rights groups have filed federal lawsuits to block the requirement that voters produce a state-issued photo ID, no one as of Friday had asked for a restraining order to stop enforcement of the law.
