My gut tells me it doesn't move the needle in his favor at all, all the polls showing Texans not loving abortion or gun policy tend not to mean much when they step onto the voting booth.
But I'm not sure that it matters either way.... there are a lot of people who are pissed and who do want answers down here. And it is really easy for GOP politicians to be insulated from criticism or dissent... the moral outrage totally fits the situation, and it is well earned, regardless of the politics.
