Better for Trump people to take over the GOP and kick the bastards out.
Impossible. The GOP is rotten to its core and unreformable. Whenever conservatives get close to controlling the GOP the Romney progressive wing of the party simply throws in with Democrats and outflanks us.
First off, primaries have only a 5% chance of success and second, if the GOP resistance continues, Trump will be the last Republican president. So the folks clamoring for Republican Party reform aren’t politically saavy.
