AUSTIN, Texas (AP) - Texas will appeal a federal court ruling that a state law requiring voters to show photo identification at the polls discriminates against low-income blacks and Hispanics.
 
Texas Attorney General Greg Abbott says he'll appeal to the U.S. Supreme Court and expects to prevail.
 
Thursday's court decision by a three-judge panel in Washington wiped out for the November election a measure championed by conservatives.
