According to the Federal Election Commission, independent organizations have reported spending nearly $3.5 million to influence the results in Arizona’s CD1.
The district stretches across northern and eastern Arizona and includes Flagstaff.
That $3.5 million is more than a million more than the republican and democrat have spent on their own campaigns.
Because of the 2010 Supreme Court decision, Citizens United, those independent groups don’t have to disclose where that money is coming from.
