The first time I ever heard Sen. Marco Rubio speak was in 2008 at a Cuban American National Foundation luncheon in Miami. Then Florida’s speaker of the House, Rubio reminded a crowd of mostly older exiles how they had become “the subject of ridicule by national publications.” A 37-year-old Rubio remarked that Cuban Americans are “the only ethnic group in America that is politically correct to attack.”

Rubio’s words stirred me, and pierced through my youthful liberalism, because I knew them to be true. Cuban Americans have been a thorn on the side of the Left for decades.
