Translation: Trump may win the Republican nomination. There is even a small chance he will be the next President. He hates much of the present Republican establishment and would demolish it. He isn't totally on board as far as unthinking support of Israel. He is bringing on board the thoughts and needs of the very low income blue collar Republicans, people who are not regarding highly by the super rich. He supports those in border states. 

Bush is out, Rubio is in charge. 
Sure, what is said here in this article is rational and reasonable. Saying "Trump’s GOP is a rear-window party pining for a white America that never is coming back" pretty much tosses those blue collar workers under the bus.
I will be voting for Bernie, but even I recognize what is happening. 
The billionaire vote is terrified of their own base, who could cost them both the Senate and the Presidency. So that base is now fair game. The support for Rubio is now mandatory.
