Regardless of whom you may support in the Democratic primary, I think donating to those who need help right now is far less controversial. The Sanders campaign is currently collecting for a group of charities geared to assist people affected by the COVID-19 outbreak. By default, anything you donate is divided equally among all 6 groups, but you can adjust that manually if you wish.
The charities are:
Restaurant Worker Disaster Relief Fund is providing direct financial support to restaurant workers in need. With restaurant closures happening in huge numbers, this fund provides small grants to workers who are out of work or with reduced hours.
The Workers Fund is providing direct aid to gig and low-earning contract workers, who have seen their income come to a halt and who don’t have a safety net.
National Bail Fund Network’s COVID-19 Emergency Response Fund is giving direct aid to organizations working during the crisis to free individuals in jails and immigration detention centers. Jails are potential hot spots for spreading the virus, and people who can be bailed out should be.
CERF+ COVID-19 Response Fund is offering a safety net and disaster aid for artists and artisans during the crisis. Protecting artists during this crisis is essential, as their income has disappeared, and sustaining the arts should always be a priority for our society.
Rent Zero Tenant Organizing Fund is supporting tenants across the country to organize and win demands for eviction moratorium and no rents during the crisis and recovery. With millions of people out of work, this is vital organizing work to protect people in need.
Amazonians United Mutual Aid Fund is organizing a mutual aid fund for Amazon warehouse workers who are putting themselves at risk during this crisis, focusing first on warehouses that have confirmed coronavirus cases but whose coworkers must still work without adequate safety protections.

It's shameful that these are necessary, but we can be proud of their efforts nonetheless. I'm sure you can track down the charities yourself if you don't want to go through ActBlue.
