In its first year of existence, the pro-Obama nonprofit group Organizing for Action raised more than $26 million, powered largely by small donations, according to a voluntary disclosure the organization released Friday afternoon.

The total is about half of its original fundraising target of $50 million, a goal that was scaled back after officials reversed their original plan to accept corporate donations amid sharp criticism.

The group, which was built out of the infrastructure of President Obama’s reelection campaign, collected $5.69 million in the last quarter of 2013. That represented a drop from each of the previous two quarters, when OFA logged around $8 million in donations.

Among the 115,730 donors who gave to OFA in the final quarter of 2013 were 49 contributors who wrote checks for $5,000 or more. Those large donations – including $250,000 from New York author Amy Goldman Fowler, $100,000 from Salt Lake City venture capitalist Ryan Smith and $90,000 from California investor Imaad Zuberi – totaled less than $1.4 million of the quarter’s haul. The average contribution for the period was $38.06.

In the last year, more than 421,000 donors have given to the group, which has sought to rally support for Obama’s stalled legislative agenda on issues such as gun control, immigration reform and environmental protections. Most recently, OFA has encouraged people to sign up for health insurance under the Affordable Care Act, seeking to counter the fallout of the botched roll-out of the federal health insurance exchange Web site.
