Story highlights Bernie Sanders' victory marks a remarkable milestone for the self-described democratic socialist

The Vermont senator tweeted "When we stand together, we win" on Tuesday night

Concord, New Hampshire (CNN) Bernie Sanders on Tuesday night notched his first win of the 2016 presidential race, defeating Hillary Clinton in the New Hampshire Democratic primary.

Sanders' victory here caps a remarkable milestone for the self-described democratic socialist. Since announcing his unlikely campaign in April, the Vermont senator has developed a cult-like following of supporters and rallied the Democratic Party's progressive base, exposing serious vulnerabilities in Clinton's candidacy.

"And that is that the government of our great country belongs to all of the people, and not just a handful of wealthy campaign contributors and their super PACS," Sanders boomed.
