Brazos County state senator Charles Schwertner was among those voting Monday in favor of changing their boundaries.
The proposed map includes Schwertner’s SD-5 getting all or portions of seven additional counties.
The Georgetown Republican would lose Grimes County to Lois Kolkhorst of Brenham.
But SD-5 would extend to the west, getting Milam, Bastrop, western Travis and Hays counties, and all of Comal, Blanco, and Kendall counties.
SD-5 would continue to serve Brazos, Robertson, Madison, Walker, Leon, Limestone, Freestone, and nearly all of Williamson counties.
