As Bernie Sanders reaffirms his pledge to contest the Democratic presidential nomination all the way through July’s party convention, one of his fundamental obstacles remains his consistent weakness among voters who identify as actual Democrats.
Results from the exit polls conducted in 27 states through the nominating contest so far show that Hillary Clinton has established a huge lead over Sanders among voters who self-identify as Democrats. Sanders, though trailing in the popular vote and delegate count, has remained competitive only because he has built a virtually identical lead among primary voters who self-identify as independents. CONT.
