I do believe that that split exists, but I don't think it's nearly as big of a deal to Republicans as liberals are trying to make it out to be. The GOP had a slam dunk way of shutting Trump out of the political system by impeaching him, and they chose not to. I honestly believe that they just don't give a shit about whether he runs for president or not, because it doesn't make that much of a difference, given that their goal is mainly obstructing any sort of progress that might weaken the influence of capital. Biden is proof that you don't need a Republican president for that.
