An explosion of “dark money” spending dominated Arizona’s 2014 election cycle, when groups that don’t disclose their donors spent millions, mostly to help elect now-Gov. Doug Ducey, two utility regulators and a handful of lawmakers.

new law passed during this past session gives further protection to the groups that spend in elections but don’t report where it comes from. And keeping track of dark money expenditures in Arizona hasn’t been quick or easy.

That’s why AZCIR decided to build @AZDarkMoneyBot.

This Twitter bot posts—in near real-time—information about which dark money groups are spending money, how much they’re spending and who the money is intended to help elect or defeat.
