Case in point: Eva Longoria, Mexican-American actress, social commentator and loyal Democrat who once mocked Republican Sen. Marco Rubio of Florida for having “silly” ideas. What makes Longoria look silly is that she believes that other Americans care what she thinks about the crisis involving Central American child refugees crossing the U.S.-Mexico border into her native Texas.
