I agree on that in general, but not in the case of Rubio.
Rubio was groomed by Jeb, Cesar Conda and others.
“Even so, Ana Navarro, a Republican political consultant and longtime Rubio friend, says she thinks there’s a big difference between Rubio and Rand Paul, a Tea Party proponent and Kentucky’s new Republican senator.”

What happens when Republicans arrive in Washington is that they’re told that working together and finding common ground is what voters want and is the best way to move the country forward. In reality, the goal posts are moved to the left more and Republicans end up supporting the narratives of the Left.
“Nonsense. Something happens when people get inside the beltway as Rush calls it, they change, and here Rubio has too.”
It’s called MONEY. Boatloads of it.
