I guess you have to be paying attention then, to see the splits. The Republican party right now is certainly not holding any sort of coalition. Liz Cheney, Murkowski, Mitch McConnell, Kevin McCarthy, and several others pretty much declared war on Trump based Republicans since 2020. They'd been opposing them long before, but they're finally out in the open about it. The democrat party also has it's own set of establishment Neocons that work to keep the populists in check. Which is why Bernie will never win a primary.
