The States Sanders Has Won Predict the Nominee More Often Than the States Clinton Has Won

"Hillary Clinton has so far won more states (18 versus 14) and amassed more pledged delegates (1,243 versus 975, per our delegate tracker) than Bernie Sanders, yet history favors the Vermont senator's grassroots campaign. The states he's won so far have correctly predicted the eventual Democratic nominee 65 percent of the time on average since 1968, according to a study of Federal Election Commission data by American University’s online analytics master’s program. That compares to 61 percent on average for states in Clinton's column."
