Unfortunately, the radical left isn't the only problem we're facing. Significant elements of the Republican establishment do not want Donald Trump to be president again. They believe that if he is defeated, it's not only the end of him, but also the end of populist conservatism.
This is not a new rift in the party. As I have outlined before, the establishment bitterly fought Ronald Reagan, too, and it has crushed other populist movements in the party.
Populist conservatism fights for the working class. It puts Main Street ahead of Wall Street. It is strong on national defense but puts America's interests first.
It believes in free markets, but not at the expense of American workers. Instead of just paying lip service to the culture war, it is serious about winning it.
In contrast, the GOP establishment wants to go back to being the party of Big Business, Gerald Ford, and the Bush dynasty, where we keep surrendering more and more ground to the socialists and Marxists.
