The RealClearPolitics average from May 6 to June 5 had Sanders at 49.7 percent and Trump at 39.3 percent. Although, the vast majority of polls showed that Trump didn’t have much of a chance against Clinton.
Sanders acknowledged the polls in May: “Right now, in every major poll, national poll, and statewide poll done in the last month, six weeks, we are defeating Trump often by big numbers, and always at a larger margin than secretary Clinton is.”
