The Dems of Rossmoor Texters in Walnut Creek, CA. offer one-on-one remote training to Get Out the Vote in key states. This group of activists claims to be the largest Dem club in the country with 1,100 paid members. Since 2018 they have sent out over 14 million texts without using personal phones, since the texting is all computer-based. Sign up at CADEMs Events.

Many other virtual events of various sorts are listed for consideration here.
For people with political passion and a need to stay safely sheltered, Grassroots Democrats HQ offers a very centralized method for volunteers to lend a hand through writing postcards from home to support a variety of campaigns across California and crucial Senate races nationwide. They provide lists of Democratic voters and appropriate scripts for specific races at various times. (The DSC will soon be able to provide blank postcards for this sort of volunteer engagement. Stay in touch for further details.)
