Millions pour into Nevada primary ads. A third of the money is untraceable.

A Nevada Independent analysis found that over a third of $14 million spent on primary campaign ads in Nevada come from groups that do not publicly disclose donors. The Service First Fund, linked to Gov. Joe Lombardo's re-election, is the top advertiser, using a 501(c)(4) nonprofit structure to avoid transparency. Republican-affiliated groups are exploiting a Nevada legal loophole to hide funders until after June primaries.
