No actual Republican candidates offered any such policies to actually build any bridges in the first place. They all supported the existing structure that enabled discrimination in the first place.
Even ‘ Rubio’ stated that he didn’t believe there was a political solution to it, making his words ring hollow, and his position identical to Trump’s and everyone else’s. His tone-deaf response was as much valid as Trump’s claim that he understood the African American plight of dealing with a ‘rigged system’, but again offered no fundamental solutions. Bernie and Hillary have offered actual fundamental political solutions such as criminal justice reform giving them credibility.
