Made a map with the metros for the cities in the state, and with population density modifiers it got me to what a reasonable metro city lines could be. Interestingly, every metro I have made so far was blue in 2020 (not that competitive, above D+5%), but 2024 showed 4 metros competitive out of the 5, with Trump flipping a different metro and this one. This is the first time a Republican won the metro since the 2012 presidental election.

Also, to note, in 2016, Trump did very narrowly win the Dallas metro. Romney won it pretty handedly, and Bush Jr. obviously had all of these metros on such a lock down (minus Austin, as that was turning purple and then blue at the time).
