Political culture explains the election, especially where it has to do with race.  If Corey Booker had been on the ticket those infrequent voters who only show up with Obama on the ticket would have made the difference in Ohio, Pennsylvania, Michigan and Wisconsin. The whites who flocked to Trump would not have picked Clinton. Sanders? Maybe, but probably not. This was a backlash election. The last hurrah for the old white people and those who follow their lead.
