Back when I was a baby republican (read: a parentally brainwashed child) and just learning about gerrymandering in school, my reaction was basically “well that’s shitty, but at least it’s the people I like doing it”.
I’m pretty sure that’s very common thinking amongst hardened republicans. I don’t even know how you convince someone to not be like that either, I just changed when I was out from under my parents boot and finally allowed to learn about the political effects of racism.
Tldr; common think pattern leads me to believe Texas is fucked until reepublicans lose their power there.
