you could check if there is an Indivisible group near you - https://indivisible.org/groups

They have been recruiting and training people to run for office all over the country and I even had someone who was a member of a chapter who lives in my complex. She had left a doorhanger with the (D) platform policies listed and it included her name and a phone number so I could contact her if I had any questions. I know they have been around for awhile (I think since 2016) but this was the first time actually running into someone who was part of it and who was living in my neighborhood.

(ETA - I live in Philly but there are chapters all over)
