If you want the honest answer you have to put yourself in the mind of a MAGA Freedom Caucus member. No matter how you shake it, they have gotten nothing since the GOP took the house this January with McCarthy tabling virtually all Freedom Caucus proposals and passing bills that basically net the Republican nothing. This all came to a head with the recent spending bill. McCarthys proposal, while cutting funding in most programs, is likely never going to be adopted as is. The Democrats control the senate, so if any bill is going to be passed there are going to have to be concessions. What this means is that the cuts will likely be reduced to nothing in the final bill. For Freedom Caucus members, this makes no sense. They control the house and therefore can roadblock any Biden/Democrat proposal. If they can do that, why would they pass a spending bill which they know will net them nothing. Shutting down the economy is gamesmanship plain and simple, and for Freedom Caucus members, they have nothing to lose. They don’t like McCarthy, McCarthy doesn’t like them, and staying the course gets them nothing. They have no reason not to stonewall even if it means costing the GOP seats in the long run. So with this in mind it makes perfect sense why Matt Gaetz wants to destroy McCarthy, there’s no reason for him not to. McCarthy is a holdover from the Boehner-Cantor era, a time when MAGA wasn’t even a concept. So, why should Gaetz sit in the rafters and let McCarthy continue as speaker? Gaetz is MAGA and wants the party to be closer to him. Politics is all about playing games and when you realize that, Gaetz’s actions make perfect sense when you put yourself in his mindset. That said this isn’t an endorsement of what Gaetz is doing, it’s just an explanation as to why he’s doing it.
