Dell is in Round Rock, Texas, in Williamson County, not Travis County (Austin). I think Williamson County is a bit more conservative than Travis County.
I know, lived in Central Texas for 36 years. Austin, Lago Vista, Leander, Manor, Canyon Lake, Pflugerville, Universal City (North San Antonio/Randolph AFB), Junction, Boerne, Kerrville, Denton, Harker Heights, Killeen/Ft. Hood, Gatesville A Short stint in Houston until I got My DL and moved outta that mess at 16 years old and moved to Austin, back when it was still a beautiful place. Barton Springs was still ok to swim in and then the developers scewed that up with E-coli, 6th Street was cool from one end to the other. They tore down Armadillo World Headquarters and put up a Bank. And then it went full tilt goofy with KEEP AUSTIN WEIRD.
Yes Williamson County is Definitely more Conservative than Austin.
There was a “Corridor Plan” that would merge San Antonio all the way up IH-35 to Georgetown so they could Tax with the “group political scam” I don’t know what ever happened to that stupid idea.
