I hope it is a win for conservatism, but we'll see. I think MAGA folks have a misguided idea of what authoritarian power a Republican speaker can wield with a narrow house majority, and Dem control of the Senate and Executive branch. His primary role in such a situation is to get unity among the house republicans to overcome guaranteed unity among house democrats, and to use that unity to negotiate acceptable small advances which can get through the Senate and POTUS. McCarthy seemed pretty well suited for that role, except for the handful of petulant children like Gaetz. Now we'll see what the petulant children can accomplish.
I don't hold out much hope, because people like Gaetz don't want to actually accomplish anything, they want publicity for their future political ambitions, and screaming "oh noes the establishments$#@!" gets a lot more traction than accomplishing things.
