James Boys, senior US policy expert and associate professor of international political studies at Richmond University, told CNBC Monday that Trump is not waging a campaign that can win the election. "If you put in someone who could reach out to Hispanics, to women, to the African American community and build on what Mitt Romney had done four years ago, maybe. "But when you see him do the exact opposite, it is impossible to see how he can win this," he said.
