In fact, Obama raised more money in aggregate from small-dollar donors — $56.7 million — than Romney raised overall.

The data cements Obama’s reputation as unusually reliant on small-scale contributors to fuel his campaign war chest. An earlier analysis by The Washington Post produced similar findings, suggesting a persistent trend in Obama’s 2012 fundraising strategy.

The new findings also come in the same week that Obama decided to embrace the efforts of a pro-Democratic super PAC, which can raise and spend unlimited funds to aid in his reelection. Advisers say the campaign has concluded that the eventual GOP nominee and allied conservative groups are likely to outspend Obama, despite his fundraising record.
