Aidan King, also known as Reddit user Vermonty_Python, is the leader of the largest pro-Bernie organization in the world right now. At just 24-years-old, King managed to grow a ragtag grassroots organization—Reddit’s Sanders For President Community—to more than 135,000 members in just two short years, an amazing feat for a recent college graduate with no formal campaign background nor experience.

Reddit has more than 80 different communities representing different states dedicated to Sanders, but the Sanders for President community is the largest and most-well known of the bunch.

Its origin was a serendipitous one. King, who is a native of Vermont just like Sanders, created the subreddit more than a year before Sanders would even announce his candidacy for president. King believes that misinformation and apathy are the two biggest issues plaguing our political system today, which motivated him to start the grassroots movement. To date, the subreddit has raised over $450,000 for the campaign.

Why is Aidan King spending so much time and energy to support Bernie Sanders? King tells Upvoted:

“He has always stood up for the middle class. He has always refrained from becoming beholden to corporate interests. He has always fought the good fight, even when it was unpopular to do so. So when Bernie Sanders says he’s going to crack down on Wall Street, end Citizens United, help out the middle class or the poor or the sick or the elderly, you know without a fraction of a doubt that he’s going to fight tooth and nail to fulfill those promises. And when I look around at the political histories of other candidates in the field, it’s disappointingly obvious that the same cannot be said for them.”

King’s work with Sanders for President has paid off, even garnering him some notoriety.

“I’m just a normal guy, fighting hard for something I care about, and much to my surprise, our whole team has had an incredible amount of success,” he explains.

NHK—the largest news broadcast in Japan—flew to his hometown and shadowed him for a day.

“That was a surreal moment —seeing an interview of mine being dubbed into Japanese! Literally all of the press myself and our group has attained is because of the way we’re using Reddit to essentially lead this grassroots movement,” King says. “We’re the largest grassroots group out of any candidate, and we’re doing it on a medium that has never been used in that way before.”

In a simple twist of fate, an interview he did with a local television news network caught the attention of Jerry Greenfield—the “Jerry” of Ben & Jerry’s.

As it turns out, King’s father Jay has worked at Ben & Jerry’s for over 20 years and has shared a friendship with both co-founders for just as long. One day, his dad bumped into Jerry in the office lobby. After hugging, they started talking about life and politics. Greenfield, of course, is also a major Sanders supporter—even entertaining the idea of creating an ice cream flavor named after the candidate.

It turns out, Greenfield had actually seen one of King’s interviews on that local Vermont television station. The next day, King received an email from Greenfield and the two got to talking about the work they’ve both done for the campaign.

Eventually, both Greenfield and his co-founder Ben Cohen pitched an idea based on a public art project titled the overpass light brigade.

“I fell in love with it immediately, ran it by the team, and they loved it as well,” King explains.

The overpass light brigade was an initiative first created in 2011. Performers, called “holders of the light,” hoist up LED signs featuring progressive political messages over highway overpasses and other public spaces.

The national group, based in Wisconsin, uses the power of light as a peaceful and creative way to protest.

After creating their own LED light–in support of Bernie—Cohen and Greenfield held it up on on overpass outside of Burlington, Vermont, sharing a picture of their sign with Reddit’s Sanders for President community. They are hoping it will inspire others to get involved in similar ways.

How can you participate? On Friday, December 18, King is organizing a massive Bernie Sanders light brigade across the entire country. So far, teams in Sacramento, Savannah, Philadelphia, Los Angeles, San Jose, New York, and DC, have already organized. If you’re interested in participating, you can fill out this Google form here.

“Why should someone else vote for Sanders? It’s entirely up to them. I’m not in the business of telling other people what decisions are right for them,” King concludes. “I can only hope that, by giving them the means to educate themselves on the issues and facts about each candidate, they reach the same conclusion that I have.”
