That might be so, but young people only decide close races because they don't like to vote. You can turn this article on its head, and say that although Bernie had a better-than-expected night, he is screwed in the long game. If he is relying on such a huge youth margin to win the nomination, he is going to feel the diminishing returns of young enthusiasm, especially after Hillary carries some more diverse states. Obama had the young vote, but it was the minority vote that won him the nomination. I'm a fan of Bernie, but I don't think he stands much of a chance. Young voters love him. Old progressives love him. But the rest of the Dems are going to feel just fine voting the brand, and nominating the first woman as a Dem candidate for POTUS.When you are so heavily reliant on support from older voters, it is tricky to project yourself as the voice of the future.
