The lawsuit, to be announced Monday morning, comes on the heels of a similar challenge filed last month against Texas. It's the latest step in the administration's push to defend voting rights after June's Supreme Court ruling that weakened the Voting Rights Act. 
The U.S. Justice Department will file suit against North Carolina’s restrictive voting law, according to reports from several news outlets. The move, which comes on the heels of a similar challenge filed last month against Texas, is the latest step in the Obama administration’s effort to defend voting rights in the wake of June’s Supreme Court ruling that weakened the landmark Voting Rights Act.
Attorney General Eric Holder was expected to announce the lawsuit Monday at a noon ET press conference.
North Carolina’s voting law, passed in July, is perhaps the nation’s strictest. In addition to requiring voters to show a limited range of state-issued IDs, it also cuts back on early voting and ends same-day voter registration, among other provisions. All of those provisions disproportionately affect racial minorities, studies show. Rick Hasen, a law professor at UC Irvine and a prominent expert on voting, has called the law “a laundry list of ways to make it harder for people to vote.”
The measure was pushed by Republican lawmakers who control the state’s legislature, and signed by Gov. Pat McCrory, a Republican. An August poll found that just 39% of North Carolinians support their state’s law, with 50% opposed.
About half of North Carolina’s counties were covered under Section 5. Since the Court’s ruling, several other southern states previously covered by Section 5, including Alabama, Florida, and Virginia, have announced plans to push ahead with restrictive voting measures.
The lawsuit’s chances are uncertain at best. It will likely cite Section 2 of the Voting Rights Act, which experts say is a weaker tool for stopping race bias in voting than Section 5, which the Supreme Court invalidated in June. Under Section 5, the federal government could block changes proposed by covered jurisdictions if the changes might reduce the political standing of minorities, as compared to the previous status quo. Under Section 2, plaintiffs need to show that an election change denies minorities an equal opportunity to participate in the political process—a far vaguer standard. And unlike Section 5, which required covered jurisdictions to submit proposed changes in advance, Section 2 is an after-the-fact remedy*.
Section 2 has rarely been used to challenge laws like North Carolina’s, Samuel Issacharoff, a law professor at New York University who has worked as a top election lawyer for the Obama campaign, told MSNBC. It was amended by Congress in 1982 to help stop at-large voting schemes, which tend to over-reward majorities and have been used to reduce minority representation.
“Section 2 makes a lot of sense in that context,” Issacharoff said. “It wasn’t drafted for this context, for how to deal with North Carolina’s very complicated racial-partisan impact [of a] change in the voting rules.”
Issacharoff added that because minorities in North Carolina are more likely to be Democrats, racial and partisan threads could be difficult to disentangle. “There’s also the problem that a lot of what has an impact on minorities, has an impact on minorities because of partisan politics,” he said.
Still, Issacharoff also noted that in 2012, courts blocked several state-based efforts to restrict the franchise, most notably in Ohio and Pennsylvania. To do so they often relied not on Section 2 but on the 14th and 15th Amendments to the Constitution itself.
“There is a renewed series of efforts, directed by the Republican party, to shut down access to the ballot,” Issacharoff said. “And so far the courts have been extremely responsive to protecting the right to vote.”
