Price us spoke at a Trump rally day before yesterday and he TRASHED HELLARY, Priebus is FULLY on the Trump train, the SO CALLED leaders in the Senate the SO CALLED Maverik, and McConnell, CRICKETS......LYIN RYAN .......CRICKETS.....BASTARDS all of them!!!!!! Priebus likes Trump I am sorry to see him leave but these BASTARDS have made it impossible for him to bring the party together!!!
My point was that the party isn't MIA, contrary to the premise of the OP. And as you point out, the party is fractured, with the Bush wing being in open revolt against Trump, and the usual duplicitous suspects like McCain and McConnell. Nobody can unite the party, and that is a good thing. One wing or the other is going to prevail.
