evidence: "Internet fundraising is about taking potential energy and converting it into kinetic energy, and nobody has done that better than Bernie Sanders," said Ari Rabin-Havt, a veteran Democratic operative who hosts a show about progressive politics on SiriusXM satellite radio. "Tim and his team are maximizing that. Their emails are superior. They really tap into small-donor psychology. Small donors go where they’re needed. If you’re a candidate who can raise all the money in the world from the establishment, they don’t think they’re needed. Bernie Sanders, his whole message is that he’s running against the establishment, and that their $20 matters." [...] Through the end of 2015, the Sanders campaign had raised $54 million in donations of $200 or less, accounting for 72 percent of its total fundraising, according to FEC filings. That’s far more total cash ― and a far higher percentage of overall cash ― from small donors than Clinton (who raised 16 percent of her $116 million from small donors) or any of the GOP presidential candidates. In fact, the percentage of cash Sanders is raising from small donors is more than twice the percentage Obama raised from small donors during his groundbreaking 2008 general election campaign, which his supporters dubbed a "small donor revolution." (To be sure, the percentage of money from small donors tends to decrease as campaigns wear on and many small donors continue giving, and ultimately cross the $200 threshold).
