On March 29, a bill overhauling campaign finance was passed by the Arizona Legislature. Among the changes to the state’s law, Senate Bill 1516 allows groups registered with the IRS as “social welfare” organizations to withhold disclosing donor information, removes spending caps on expenditures for political fundraisers, and allows for candidate to candidate transfers of campaign funds.

While the lack of requiring disclosure of political donors was a major objection from state legislators opposed to the bill, the majority of the Legislature was willing to accept the changes. “I think transparency is a good principle. But it is not the overarching principle,” said bill supporter Rep. J.D. Mesnard, as reported by the Arizona Daily Star. If not vetoed by Gov. Doug Ducey, the law becomes effective January 1, 2017.
