The National Right to Work Legal Defense and Education Foundation ran TV and radio ads during last year's educational voucher referendum campaign, offering legal aid to anyone who was coerced into signing petitions supporting the referendum.

State law says that anyone attempting to influence voters must disclose the money they spent on the effort. But the NRWLD&EF refused to file, citing freedom of political speech, even though the spots promoted vouchers and were a slap against the teachers' unions.

The suit is striking only because it indicates Gary Herbert's office actually attempted to enforce Utah's ineffective disclosure. Why do these groups — and the anti-voucher groups pulled similar things — loathe telling us about their money and where it comes from? It makes voters wonder what they are hiding.
