I would say there are three major factions: The Establishment Wing (Country Clubbers), The Trump Wing, The Conservative Wing
While there is some intermixing, some who try to have a say in more than one wing, those 3 define different fundamental principles and priorities.
In your assessment, what are the Characteristics of the Trump wing...politically? (Not the typical dumb, rude, liberal etc.)
Are there POLICY differences? Will they be able to garner a majority of GOP primary voters and/or majority in the General?
I would describe the Republican coalition as follows:
The old Eastern moderates, like Rockefeller.
The western libertarians, like Goldwater.
The southern religious conservatives, like Jesse Helms.
The strong defense internationalists, like Cheney.
The intellectual fusionists conservatives/libertarians, like William Buckley.
Some movement exists back and forth between the groups and some belong to more than one group.
