Correction note: This article originally said that Open Primaries spent $300,000 in support of the donation disclosure initiative. It was the coalition in support of both initiatives. The article has been corrected.

Salon reported Thursday that a campaign to adopt nonpartisan elections in Arizona suspended its efforts after a major donor dropped out.

Texas billionaire John Arnold had contributed at least $1 million in support of the campaign to adopt a nonpartisan, top-two open primary similar to the systems in California and Washington state through the organization Open Primaries. He later learned that nearly half of his donations were going toward another initiative.

This second ballot measure would require that groups who spend money to influence elections disclose any donations exceeding $10,000. The coalition in support of both initiatives spent $300,000 of his donations in support of this initiative.

Arnold voiced his opposition to this funding and $178,000 of his donation was returned this week. The two former Phoenix mayors who were benefiting from Arnold’s contributions have suspended their campaign in support of the nonpartisan, top-two primary until they can find alternate sources of funds.
