“The establishment will not take it away from Trump. They simply will nominate and then campaign against him in GE.”
I agree if Trump gets the nomination they will work against him. However, if he prevails in the general election, the establishment will be forced to deal with him or bolt the party. If he loses, we go back to status quo with the establishment running “safe” candidates every four years who lose.
The current immigration patterns and resulting demographic wave, with organized block voting, will ensure Democrat victories for decades under the current two party system. Even if conservatives were able to wrest control of the Republican Party from the big government enabling establishment a pure conservative party will not be able to secure a majority of the national vote when ethnic blocks comprise 30-40% of the population and half the people in the country pay no taxes and receive government checks. Splitting the vote three ways is the only way going forward for conservatives, and defenders of individual liberty, to wield political power.
The sooner the GOP is split the sooner a pure conservative party can be created and offer a real alternative to the leftist socialist democrats and the globalist big government Republicans.
