ActBlue

ActBlue is an ASP (application service provider) and users access all its services through the company's website at www.actblue.com, so there are no setup costs. Campaign supporters can start a page on the site and start fundraising immediately. The site also supports "community fundraising," in which a campaign can invite others to set up their own fundraising pages, effectively creating a networked community of fundraisers rather than a traditional centralized fundraising model. This strategy is geared equally toward small and large campaigns. Small campaigns benefit by using ActBlue pages as their main web pages, and can start fundraising immediately. Larger campaigns benefit by giving fundraising control over to a community of supporters, engaging their supporters more deeply than a centralized website would.
In addition, members of the community can nominate -- "draft" in ActBlue parlance -- candidates for office and raise draft funds for that candidate. Those funds are held in escrow, and if the candidate decides to run, they will be given given to their campaign; if not, they will be given to the Democratic National Committee.
Fundraisers or organizations can also fundraise for multiple campaigns at a time by creating a fundraising page featuring several endorsed candidates. "From the donor's perspective it's a one-time credit card transaction," says Rahn, so this is an attractive option for campaigns who endorse multiple candidates.
