Here, I'm trying to join the "Registration Ready" list that says why people were on the purge list with the 2022 data set that shows how each voter was registered. I want to figure out how many of the voters registered by certain organizations, particularly Black Fork Strategies and Ohio Organizing Collaborative, were more likely to end up on this year's purge list. Unfortunately, the keys I've created in both data sets don't seem to be compatible for some reason, because I have found matches in this data set searching by hand.
