Electoral

The Electoral extension supports three different electoral lookup services: Cicero, Plurality (formerly Open States) and Google Civic. You can choose the one you want, obtain an API key from the service, and then configure it in CiviCRM.

Once configured, you can create a lookup job that specifies a group of contacts to be districted. When the job runs, it will lookup each contact's address and then update that contacts electoral custom fields with the district in which each address is located.
