I recall speculation that she is voting this way because she is expecting to be given a seat that leans much more to the right.
That makes sense. I suspect Republicans are going to try to shore up not only her, but also Taylor, Crenshaw, McCaul, etc. and perhaps create an additional seat or two that will lean their way. They would be well advised to create one Democratic seat for the majority of Travis County. That would take a number of congressional districts out of contention for Democrats. Beto O'Rourke was able to come within single digits in several of them in 2018 thanks to his dominating performance in Travis.
If they were smart, they would pack most of Austin into a democratic sink that doesn't go down to San Antonio.
Then they could have John Carter's northern suburban district (Williamson County) be purplish.
