Senator Bernie Sanders (I-Vermont) drew an estimated 18,000 supporters to his rally at the Colorado Convention Center on Saturday night - nearly double the size of his rally held in October at the University of Colorado in Boulder.

Supporters waited in long lines to get into the Bellco Theatre to attend the event, which was banking on Sanders' win over Hillary Clinton in the New Hampshire Democratic primary. Sanders touched on economic disparity, social equality, and the "broken" criminal justice system at the rally.

"Here is a radical idea, we're going to create an economy that works for working families, not just the one percent," said Sanders. "The reason people are working so many hours in this country is that wages are just too low."

Following the rally, both Sanders and Clinton attended and spoke at the Colorado Democratic Party's annual fundraising dinner, where 1,500 people paid at least $150 each to attend.
