A popular culprit is former Massachusetts Governor Mitt Romney. His crime? Welcoming Trump's endorsement in Romney’s own race for president in 2012. . . Romney didn’t seek Trump's endorsement because he thought it was worth having so much as he wanted to prevent Trump from making a disruptive kamikaze run. By sidelining Trump, Romney kept Trump's politics from entering the nation's bloodstream for another four years. If only today's Republican leaders could have done the same.
