The Democracy Alliance was launched after the 2004 election by Soros, the late insurance mogul Peter Lewis, and a handful of fellow Democratic mega-donors who had combined to spend tens of millions trying to boost then-Sen. John Kerry’s ultimately unsuccessful challenge to then-President George W. Bush.

The donors’ goal was to seed a set of advocacy groups and think tanks outside the Democratic Party that could push the party and its politicians to the left while also defending them against attack from the right.

The group requires its members — a group that now numbers more than 100 and includes finance titans like Soros, Tom Steyer and Donald Sussman, as well as major labor unions and liberal foundations — to contribute a total of at least $200,000 a year to recommended groups. Members also pay annual dues of $30,000 to fund the DA staff and its meetings, which include catered meals and entertainment (on Sunday, interested donors were treated to a VIP tour of the recently opened National Museum of African American History and Culture).

Since its inception in 2005, the DA has steered upward of $500 million to a range of groups, including pillars of the political left such as the watchdog group Media Matters, the policy advocacy outfit Center for American Progress and the data firm Catalist — all of which are run by Clinton allies who are expected to send representatives to the DA meeting.

The degree to which those groups will be able to adapt to the post-Clinton Democratic Party is not entirely clear, though some of the key DA donors have given generously to them for years.

That includes Soros, who, after stepping back a bit from campaign-related giving in recent years, had committed or donated $25 million to boosting Clinton and other Democratic candidates and causes in 2016. During the presidential primaries, Soros had argued that Trump and his GOP rival Ted Cruz were “doing the work of ISIS.”
