As a matter of practical politics, I favor exemplary punishments of unreliable RINOs but not purges or mass expulsions. More than once over decades in conservative politics, I have seen RINOs fall into line once it was made clear that they were no longer in charge. If this seems less than fully satisfying, one might consider that the goal is not purity but to attain and keep a majority in order to run the country.
exemplary punishments? Never gonna happen. Of course, it’s just as easy for you to say that the party never gonna split.
At some point in time, the centre cannot hold. RINOs like to think they’re the center of the party but they aint. They’re just assistant democrats.
