Yes, he can. Hispanic turnout being higher will make it more challenging this time around, but squeaking by again is not out of question. But after 2020 redistricting, his district is likely to get more Democratic (more of El Paso County) unless they stretch it into the Midland/Odessa area instead of going down to Del Rio and outer San Antonio.
Depends on the VRA anyway. If it is gutted to significant amounts like Dems claim I think the GOP might just go for the double sink Austin(white liberals are the worst thing for the Texas GOP they will turnout and they will vote D in absurd amounts) and gut other districts like this by making it go into more rural areas.
