Bernie Sanders is picking up steam in the race for the White House — driven in part by a populist, anti-Wall-Street message, and seen by many as an antidote to the familiar faces that dominate the 2016 race.

Alongside his own campaign efforts, a grassroots movement is gaining traction on social media.

Supporters have rallied support on Twitter under the hashtag #FeelTheBern, which has proven popular. In the past 30 days, according to tweet tracking site Topsy, the hashtag has been used more than 212,400 times.

Burlington Beer Company, based in Sanders home state of Vermont, have even begun printing #FeelTheBern on the bottom of their beer cans.

While Democratic frontrunner Hillary Clinton is using her primary campaign to reintroduce herself to the American public, Sanders sits on the other end of the spectrum.

The Vermont Senator seen as a champion of liberal causes has recognized the power in recognizing his supporters.

"I have a lot of respect and admiration for Barack Obama," he said told the Daily Beast in a May interview, but the "biggest mistake" he made after running "one of the great campaigns in American history" was saying to the legions of people who supported him, "thank you very much for electing me, I'll take it from here."

"I will not make that mistake," Sanders added.

Sanders is blowing the competition out of the water on Reddit. The subreddit /r/SandersForPresident is dominating with some 64,772 subscribers as of Monday. In comparison, the primary reddit for Clinton supporters, r/HillaryClinton, has 370 subscribers. Neither campaign has an official presence on the site.

The Sanders social media initiative seems more organic than those of Hillary Clinton and other high-profile, big money contenders who have invested heavily in their social media campaign — and the content of which is generally created in-house.

Clinton was mocked last week for an awkward Vine about her "chillin" in Cedar Rapids between campaign event. Somehow, Clinton doesn't come across as the chillin' type.

The New York Times recently asked the Clinton campaign if it was concerned about the buzz around Sanders:

There are plainly concerns within the Hillary camp about an ‘‘enthusiasm gap,’’ especially given the recent crowds, money and attention Sanders has been drawing. When I asked [Clinton strategist Robby] Mook about the challenge of keeping Clinton supporters excited, given how familiar the candidate is and the glide path she appears to have to the nomination, he became defensive. ‘‘I take issue with the excitement question,’’ he told me, noting that they have ‘‘more social media activity than any other candidate.’’ He added, again, ‘‘I take issue with the premise of your question.’’

While Clinton's campaign may beg to differ, the stats, at least on Twitter, speak for themselves. Trailing the #FeeltheBern hashtag, #ChillaryClinton has only been tweeted 160 times in the past 30 days based on statistics from Topsy.

The grassroots nature of the Sanders campaign is also seen in its physical attendance. Earlier this month, Sanders drew in the largest crowd of any candidate so far during the 2016 race when 10,000 people attended a rally in Madison, Wisconsin.

On Sunday evening, Sanders packed an arena at the University of Houston with supporters, just hours after holding an even larger midday rally in Dallas.

According to figures released by Sanders' campaign, 5,200 people filled the university arena and another 8,000 attended the event in Dallas. He is consistently drawing large numbers into his campaign rallies, outpacing all the high-profile GOP candidates.

The power of the grassroots movement is not just visible in the numbers coming out for Sanders' rallies. It's also shown in the fundraising efforts since he first launched his campaign in March.

Between April 30 and July 1, the Sanders campaign raised more than $15 million from 250,000 donors, many of whom made small contributions online.

FEC reports show that small donations, under $200, account for more than three-quarters of the $13.7 million in contributions he has collected. Sanders also transferred $1.5 million from a now-dormant Senate campaign account.
