AUSTIN, Texas (AP) — A major election year in Texas has overshadowed an upcoming trial on the fate of the state’s tough new voter ID law, with a judge set to determine whether it safeguards ballot integrity or discriminates against minorities by imposing a mandate that suppresses turnout.

U.S. District Judge Nelva Gonzales Ramos in Corpus Christi will begin hearing arguments Tuesday on one of the nation’s most stringent voter ID measures, which Republican Gov. Rick Perry signed into law in 2011.
