It was more like a pep rally than a political rally on Thursday.
All 2,300 seats at the Lied Center were full. Thousands of Bernie Sanders supporters never even made it inside.
“We excepted maybe 2,000-5,000, people and I’m hearing estimates that we had over 10,000 people," said Sanders Campaign Volunteer Michelle Allen.
Some in attendance aren't even old enough to vote.
“I feel like Bernie's campaign isn't just a campaign for presidency, it's a movement," said high school student Braxton Adrian.
Others in the crowd weren’t even democrats.
"I’m not optimistic about our party's nominations, so I wanted to be a little more informed,” said republican voter Erin Weides.
Sanders touched on a number of environmental issues including climate change and the Keystone XL Pipeline.
“When I’m elected president I will tell them pack up, get out, there will not be a Keystone Pipeline,” said Sanders.
The crowd erupted when sanders mentioned raising the minimum wage to $15 an hour and closing the economic gap.
“There is something profoundly wrong in this country when people in the middle class are working longer hours , for lower wages, scared to death about the future of their kids,” said Sanders.
An affordable future was another hot topic.
“I can’t afford college,” said one Sanders supporter.
Sanders is pushing for public colleges and universities to be tuition free.
“Many of these students are going to leave school 40-50,000 dollars in debt,” said Sanders.
Millennials are flocking to Sanders rallies to hear him speak.
“They're idealistic, that's what happens when you’re young and you look at this country and ask why do we have an economy that is so unfair,” said Sanders.
Many young people are encouraging their peers to back Bernie.
“Think about your future, this campaign means a lot for your future,” said a Sanders supporter.
After an energetic rally, Bernie Sanders left many feeling optimistic at the future, even some republicans.
“You know while I’m not like ‘Feeling the Bern,’ well I am a little,” said Republican Erin Weides.
Sanders told KMTV Reporter Emily Szink that if voter turnout is high on Saturday then he has a good chance of winning Nebraska, but if it's low, he'll struggle.
