Senator Bernie Sanders’ campaign is making massive waves in the Democratic presidential nomination drawing some of the largest crowds of the 2016 election cycle. Sanders gave a passionate speech to a crowd estimated to be more than 5,000 at the University of Denver on Saturday night.

Sanders came out to Neil Young’s “Rockin’ In The Free World,” with the approval of the Canadian management and delivered a speech on the decline of America’s middle class and the redistribution of wealth in the United States.

Bernie Sanders, like his chief opponent Hillary Clinton, has spoken out against the income gap and how it favors the wealthy within the country. However, unlike Clinton, Bernie Sanders is not backed by the established with his top donors, mainly made up of workers union such as the Machinists/Aerospace Workers Union and the Teamsters. In stark contrast, Hillary Clinton has been backed by contributors such as Citigroup Inc and Goldman Sachs.

Sanders reflected away from the spotlight as the crowd in the university gym changed his name. Instead, the Vermont senator was quick to point out that the Bernie Sanders campaign was not about himself. “This campaign is not about me,” Sanders said.

“It is not about Hillary Clinton or any other candidate. This campaign is about you, your kids and your parents. It is about creating a political movement of millions of people who stand up and loudly proclaim that this nation belongs to all of us and not just a handful of billionaires.”

The polling is now reflecting how strong Sanders momentum is beginning to look. Hillary Clinton had been a strong favorite not just in the Democratic presidential primaries, but also among all candidates across both parties. With her name recognition many had tipped her to easily win the democratic nomination. In New Hampshire, Sanders is now 10 percent behind Clinton, a healthy lead for the former first lady but no longer a commanding one.

At this point, Bernie Sanders campaign is still looking like an out shot of being successful with the Vermont senator still trailing behind Clinton in Iowa but as the weeks and months quickly passes by his campaign may just spring the surprise of the election campaign.
