Rep. Paul Gosar, an Arizona Republican, told Mike Huckabee on Monday that the U.S. should consider a “national referendum” to make voter registration more difficult.

The two were discussing the Supreme Court ruling that invalidated an Arizona law mandating that people registering by mail to vote in the state using a federal voter registration form produce additional documentation to prove their citizenship. The federal form already requires voters to certify under oath that they are citizens. Civil Rights groups worried that the Arizona requirement would disenfranchise low-income voters and jeopardize voter registration drives.

Gosar told Huckabee that the ruling, which found that Arizona’s requirement was preempted by federal law, was “very disappointing,” adding, “We really have to solve this process from the federal level, with regards to either legislation or a national referendum.” It is unclear what he meant by a “national referendum.”

Gosar also lamented that the Department of Justice under Attorney General Eric Holder has “upheld or disdained certain groups’ privileges over others,” echoing Justice Antonin Scalia’s dismissal of the Voting Rights Act as a “racial entitlement.” (Scalia, however, wrote the opinion striking down the Arizona law.)
