The "Republican base" is largely on the sideline. THEY were replaced by the NEW "base"............. TP-ers, Supremacists (closeted and Out!), The Anti-Immigration crowd, and conspiratist tin foil hat wearers. A battle for the "GOP" is brewing. Once Trump has been dethroned you'll see the clamor begin, and the battle commence. There are many "champing at the bit" to try and be the NEW Republican rising up to claim leadership. Guys like Ben Sasse, Kasich, Flake, even Romney and that little twit from Florida Marco (little Marco) Rubio will try and take advantage of the Emperor's dethronement.
There are no shortage of Brutus's in the Republican party!
