The RNC is not the DC establishment so how will Trump protect himself and his campaign from the powers behind the DC establishment attacks against him?
The DC Establishment was/is going to attack any conservative who shows strength.
In fact, the DC Establishment was/is going to take down even any RINO that would happen to get the GOP nomination.
How about an RNC pledge, ‘we promise to support all candidates equally with fairness and let the American electorate choose the nominee within the process’.
