Arizona Gov. Doug Ducey has signed a measure that significantly expands anonymous political spending in Arizona elections.
The proposal by the secretary of state that was touted as a housecleaning measure increases the influence of dark money groups that can spend money on elections without revealing their donors.
The campaign finance re-write doubles the amount these groups spend on ballot measures and allows nonprofit groups to spend more money influencing elections without having to reveal donors.
It also allows politicians to give campaign contributions to each other in a move critics call the "kingmaker provision."
Ducey was one of the largest benefactors of dark money in 2014 elections.
He says the re-write simplifies regulations and provides more opportunity for participation in the political process.
