You're bound to fit in somewhere here:
Movement Match- In November, a group of friends–most of them longtime activists–got together to console one another in aftermath of the election. “We started talking about what keeps us going in the face of hard realities. We realized that what gives us hope and energy to keep going with our work is the fact that we are members of activist groups,” says Talia Cooper, who co-founded the project with Pippi Kessler, Sonia Alexander, and David Mahfouda. “We realized that a lot of people got activated since the election, and some of them say that they’re not sure what to do. So we’re working to direct people who are new to the movement to organizations led by experienced activists and seasoned organizers.”
That group appears to be a good place to start, if you're not sure where you'd be best utilized. And here's another good one, if you're really feeling froggy:
Run for Something- This organization, launched January 20, is committed to recruiting and supporting millennials running for down-ballot offices. “If you’re a young progressive who’s not necessarily part of the system or familiar with politics, there was really nowhere for you to go to ask for help if you wanted to run,” says Amanda Litman, a former Clinton campaign staffer and co-founder of the group. “Candidate recruitment is a time-intensive activity that requires a lot of manpower and resources, and it’s something that the state parties and state committees just couldn’t do properly because they’re already doing so much. So we’re trying to fill that gap.”
Millennials who want to get into electoral politics will be able to access training, pick the brains of experienced mentors, and in some cases get help with funding and staff. Litman says that in less than two weeks since the project’s launch, they’ve signed up almost 3,000 young candidates to run for local office. She says that the group didn’t expect the response they’ve gotten, and are now building out infrastructure to handle the demand.
Check it out, the list of groups (with links) is already yuge, the very best list, no other lists can even handle its yugeness...Sorry. There's enough Trumpiness already going around, and I shouldn't encourage it. ;)
