 With your help, we are going to win the Democratic nomination. Big day for presidential hopeful Bernie Sanders. The longtime independent declared himself a Democrat as he filed paperwork for the New Hampshire primary, which is the first in the nation presidential primary ballot. After the filing, the Vermont senator spoke to a crowd of about 750 outside the New Hampshire statehouse, and he reiterated some key points in his campaign. I will not be the president of a country that has more people in jail than any other country. I will be the president of a country which has the best educated population on earth. Let none of us forget 11 million undocumented people in this country who deserve to be taken out of the shadows, who deserve a path towards citizenship through comprehensive immigration reform. Sanders also touched on college affordability and universal health care, but his final message was directed towards the one percent. Enough is enough. This country, this country and our government belong to all of us, not just a handful of billionaires. Now that Bernie Sanders is on the New Hampshire primary ballot, he can now focus his attention on Hillary Clinton, who is leading him in New Hampshire polls by three percentage points. Clinton will be here on Monday to book her spot in the same primary. Reporting in Concord, New Hampshire, I'm Brandon Lewis for the BU News Service.
