Yes, Hillary won a squeaker in Iowa, yes, Bernie Sanders will win in New Hampshire. Yes, Bernie is gaining support from young voters. No, Bernie cannot gain the support of white males, no, Bernie can not gain the support of white union members, yes, Hillary Clinton can do much better among such voters. As of this moment, neither in Iowa nor in New Hampshire has an election taken place in a state which contains black or Hispanic voters and large blocs of union members.
Hillary will not win in New Hampshire but she will win in South Carolina and in large industrial states. Those are the numbers that count. For the coming months the Sanders movement will inspire young voters to enter the fray. The unanswered question is whether this bloc will actually turn out to vote on election day. They never showed up in 2010 nor in 2012 and that is why Republicans control Congress.
