Secretive Nonprofits Back Governors Around The Country

Optics aside, Greitens isn't the only governor connected to supportive nonprofit organizations.

Groups in Arizona, Illinois and Georgia have sprung up to help the states' governors, while avoiding traditional donation requirements. Robert Maguire of the Center for Responsive Politics said the groups are the "unlimited, undisclosed arm of the administration that basically … bolsters the agenda of the governor."

Many 501(c)(4)s were created over the years to help push specific issue or ideological causes. But more recently, the state-based nonprofits came to life to help individual candidates. Since most states don't require 501(c)(4) to reveal much about what they're doing, they've become increasingly popular fundraising mechanisms to help governors.
