ALICE, Texas -- A South Texas state House race may hold clues to how successful Republicans can be at winning over Hispanic voters in the future.

The tight contest for Texas House District 43 takes place in a predominantly Hispanic area west of Corpus Christi that the GOP has historically conceded on Election Day.
