The establishment republican party has already started to dissipate, the stars of the republican party are not establishment, heck the new republican party is on the VP slot, for the last two elections. This president runs against the VPs because they are who their real opponents are. I will expect to see more real conservatives seek and take office in the party as each election cycle takes place. The real problem with the establishment is they don't believe what they say they stand for so they can't talk without sounding like blubbering idiots. Those who believe what they say they stand for are better equipped to articulate and defend the reasoning of thier positions and ideas.
