Bernie Sanders has broken the fundraising record for most contributions at this point in a presidential campaign, surpassing 2.3 million donations.
According to a Dec. 20 post on Sanders' campaign website, the previous record-holder was Barack Obama, who had logged 2,209,636 donations by Dec. 31, 2011 during his reelection bid. Many of these contributions are from small donors: according to the Sanders website, the average donation that came in during the third Democratic debate on Saturday was less than $25.
Sanders raised more than $26 million in the third quarter of 2015, according to the New York Times.
As TIME's Sam Frizell reported in September after learning of strong fundraising numbers for the Vermont Senator, "Sanders routinely points to his average donation size and number of contributors as evidence that he is building a grassroots 'political revolution.'"
