US Voters site https://voterrecords.com contains public information. Each record has the voter’s name and other info such as addresses, and, potentially, emails, phone numbers, and gender. The site has the data for sixteen US states. For many professionals who are not on LinkedIn or are barely online altogether, the voters’ info provides Sourcers with a way to reach out to them.
