Tuesday's Pennsylvania primary election comes on the heels of the Brooklyn-born candidate's double-digit loss in New York. Sanders may be in increasingly desperate shape as he trails Clinton in both the popular vote and delegate tally, which will decide who wins the Democratic nomination at the convention in Philadelphia this summer, but his support among younger voters has been unwavering. An NBC News/Wall Street Journal poll released last week showed Clinton with 50 percent of the vote and Sanders with 48 percent. But the age divide is clear. Among those 50 and over, Clinton led by 27 points. For those under 50, Sanders was ahead by 31 points.
