> The state of Texas as a whole is not going to do that.
What makes you so sure of that? Texas has a huge middle and working class. If asked I bet majority of Texans wouldn’t mind taxing their upper class. I think it is only a matter of time before politician is able to win over this vote share by targeting the state’s richest for taxation.
It doesn't matter the changing makeup of the state when the republicans have gerrymandered it to be unwinnable. Sure, it might go blue a few presidential elections, but for policies that actually come from the statehouse it will be blood red for the foreseeable future.
