Well, 15% for Bernie is at least good enough to win some delegates. As long as he gets above 15% everywhere, he'll get a decent share of delegates.
On the GOP side….Trump-mentum continues. I wonder what his numbers would be in New York.
15% is a good start for Bernie at this point in a heavily minority state like NJ. Once he wins IA and NH and gets the big "mo" and minorities get a sense of how much better than Hillary he is, he has the potential to double or triple the 15% by the time of "Super Tuesday".
