The justices are still considering a case that could potentially invalidate a key provision of the Voting Rights Act, but Arizona Republicans are already pushing legislation that’s unlikely to survive contact with the landmark voting rights law if it is not struck down by the Court.

The Arizona Senate recently passed a bill which makes it a felony for anyone working or volunteering on behalf of a political committee or other organization to deliver mailed ballots to a polling place — a bill which could significantly undermine voter turnout efforts in Latino communities. Arizona is one of nine states that must, because of the Voting Rights Act, submit any new voting law to the Justice Department or a federal court to ensure that the law “neither has the purpose nor will have the effect of denying or abridging the right to vote on account of race or color.”
