I've still yet to see an example of this hypothetical person you're alluding to, who is genuinely working towards this change in the gop? It is really only oppositionist and temporary.
Liz cheney, for example, seemed to be something approaching this during impeachment, but she was just fighting for her political life and saw her only angle. And of course, in the same breath she'll say that "liberals are aborting babies after they are born".
