Will not happen. The GOP has structured itself internally specifically to prevent this from happening. Which is why it has not happened already, despite a decade or more of "applying the whip" to the already-existing GOP.

Again, some objective media sources with decent demographic penetration would solve this problem.
You are 100% right.
