On November 8, Arizona voters will decide on a campaign finance ballot measure that would require disclosing names of original campaign donors.

Proposition 211 would require that anyone making independent expenditures of more than $50,000 on a statewide campaign or $25,000 on a local campaign to disclose the names of the money’s original sources, which would be defined as the persons or businesses that earned the money being spent.

Organizations that fail to disclose would face a fine equal to the amount contributed, or up to three times that amount.

Proposition 211 would apply to corporations, nonprofit groups and charities that currently are not required to disclose the names of the people who give money to political campaigns that the organization backs.

The proposition would pertain only to spending on political advertising and would be administered by The Citizens Clean Elections Commission.
