Rep. David Livingston said Rep. Isela Blanc should fully comply with any investigation into allegations she or others doctored petitions to help get a referendum of school voucher expansion on the ballot, and if she’s found in the wrong, resign from office.

With validation results in from Maricopa County, “it’s a mathematical guarantee” that the referendum on school voucher expansion in Arizona will make it to the 2018 ballot, Secretary of State Michele Reagan said in a tweet Tuesday.

A Maricopa County Superior Court judge heard arguments in a case that will not only determine whether the Citizens Clean Elections Commission can investigate Attorney General Tom Horne, but whether it will be able to investigate any candidates who aren’t part of Arizona’s public campaign funding system.

Despite finding that at least seven signatures collected by Toby Farmer’s campaign for the state Senate were forged, a Maricopa County Superior Court judge ruled that there was no evidence to suggest Farmer himself committed the forgery.
