Senator Ted Cruz (R-TX) is of Cuban descent. His father fled the brutal dictatorship of Fidel Castro. Senator Marco Rubio (R-FL) is of Cuban descent as well. His parents fled Cuba before Castro came to power but the could never return thereafter. In essence, the parents of both men know the evil Castro wrought. To this day, the both preach against the communist ideology.
That is why it is so inexplicable to see both of these men lower the bar for political correctness by heaping praise on the now deceased Nelson Mandela, a man who had great reverence for Castro.
