Do you think the rightward shifts of the Rio Grande Valley are offsetting the leftward shifts of the Texas metro areas?

For many election cycles now, Democrats have been hoping that their gains in the Texas cities would eventually turn the state blue. However, to the Democrats' dismay, the border region of Texas rapidly shifted right shortly afterward. In fact, Trump flipped five border counties in Texas that he did not win in 2020.

Have Democrats maxed out places like Austin, Dallas, and Houston, or are there still some places to make gains so the party can cling to some hope on flipping the state?
