RALEIGH, N.C. — North Carolina’s Republican governor is promising to fight a lawsuit by the US Justice Department challenging the state’s tough new elections law on the grounds it disproportionately excludes minority voters.
Governor Pat McCrory said Monday he has hired a private lawyer to help defend the new law from what he suggested was a partisan attack by the Obama administration.
‘‘I believe the federal government action is an overreach and without merit,’’ McCrory said at a brief media conference during which he took no questions. ‘‘I firmly believe we have done the right thing. I believe this is good law.’’
North Carolina’s new law cuts early voting by a week, ends same-day voter registration, and includes a stringent photo ID requirement. The measure also eliminated a popular high school civics program that encouraged students to register to vote in advance of their 18th birthdays.
More than 70 percent of African-Americans who cast a ballot in North Carolina during the past two presidential elections voted early. Studies show minority voters are also more likely to lack a driver’s license.
Attorney General Eric Holder said on Monday that his agency would show in court that the intent of the North Carolina law is to suppress voter turnout, especially among minority and low-income voters.
‘‘By restricting access and ease of voter participation, this new law would shrink, rather than expand, access’’ to voting, Holder said. ‘‘Allowing limits on voting rights that disproportionately exclude minority voters would be inconsistent with our ideals as a nation.’’
Battle over state’s election overhaul
The lawsuit, filed at US District Court in Greensboro, is the latest effort by the Obama administration to counter a Supreme Court decision that struck down the most powerful part of the landmark Voting Rights Act of 1965.
The 5-to-4 decision handed down earlier this year freed states, many of them in the South, from strict federal oversight of their elections.
Within days of the Supreme Court ruling, North Carolina’s Legislature ‘‘took aggressive steps to curtail the voting rights of African Americans,’’ Holder told reporters, calling it ‘‘an intentional attempt to break a system that was working.’’
Phil Berger, the state Senate president pro tempore, and House Speaker Thom Tillis issued a statement that rejected Holder’s argument.
‘‘The Obama Justice Department’s baseless claims about North Carolina’s election reform law are nothing more than an obvious attempt to quash the will of the voters and hinder a hugely popular voter ID requirement,’’ they said.
‘‘The law was designed to improve consistency, clarity, and uniformity at the polls and it brings North Carolina’s election system in line with a majority of other states,’’ the lawmakers said. ‘‘We are confident it protects the right of all voters, as required by the US and North Carolina constitutions.’’
McCrory’s office said Monday he had retained lawyer Karl S. ‘‘Butch’’ Bowers Jr. to defend the GOP-backed elections changes. Bowers served in the Justice Department during the administration of President George W. Bush.
In addition, the state’s Republican-run Legislature has also hired outside legal counsel at taxpayers’ expense to defend the new law. Attorney General Roy Cooper, whose office typically takes the lead on defending the state in court, is a Democrat who may seek to challenge McCrory for governor in 2016, as the ID requirements are due to take full effect.
Democrats and civil rights groups argue the tough new laws are intended to make voting more difficult for minorities and students, voting groups that lean toward Democrats, in states with legacies of poll taxes and literacy tests.
North Carolina is among at least five Southern states adopting stricter voter ID and other election laws. The Justice Department on Aug. 22 sued Texas over the state’s voter ID law and is seeking to intervene in a lawsuit over redistricting laws in Texas that minority groups consider discriminatory.
As in those other states, North Carolina Republicans have said that voter ID requirements are needed to combat in-person voter fraud, which they claim is endemic.
Records show most criminal prosecutions for voter fraud in the state involve absentee ballots, which the new GOP-backed law actually makes easier to obtain and which do not require any sort of ID. State statistics show Republican voters are more likely to cast absentee ballots than Democrats.
Holder specifically pointed to the lack of evidence showing voter fraud is a big problem in North Carolina as an indication the real goal is partisan gain.
‘‘We’ve looked at these laws across the country,’’ Holder said. “They have a disproportionate negative impact on people who are young, people of color, people who are poor, and I think at a minimum have a partisan basis to them.’’
