Our skilled editors keep track of up to 22,000 candidates in an election cycle, including filing deadlines, gathering data, and getting that data to our customers quickly. Whether you sell products or services to candidates or are a web developer looking to build a sample ballot, our reliable and continuously updated data, in several formats, will keep you coming back time and again.

Candidate Data Service

This data subscription service is perfect for campaign professionals who need updated data throughout the election cycle. Each weekly file includes two special tabs – the first details all changes made to the file since the previous week’s file delivery, and the second contains candidates added. Everything you need to keep up with candidates as they move through the election process.

 

Candidate Web Service

This subscription option is a web-based API that is easily consumable using JSON or XML. You select the level of service. You control the usage. You control the design. The perfect service for app developers and website enhancements.

 

Candidate Mailing List

Our self-service mailing list tool is for those looking for a one-time mailing list or datafile. Build your list using a simple interface and predefined filters for access to all candidate information available at the point in time you purchase your list. Then select either a simple mailing list file or a more extensive datafile, download your list, and it’s ready to use.
