The Department of Justice has entered the political fray, opening an investigation into Pennsylvania’s voter ID law.

According to reports, a three-page letter was sent to Pennsylvania Acting Secretary of the Commonwealth Carol Aichele asking that the state release a complete voter registration list including race and voting history, as well as a listing people with valid state identification.

In seeking the list, the Justice Department wants to make sure that Pennsylvania is not in violation of Section 2 of the Civil Rights Voting Act, which prohibits voting practices or procedures that discriminate on the basis of race, color, or membership in a particular language minority group.

The Justice Department has blocked Texas and South Carolina from requiring voters to show ID at the polls. Both states are challenging that ruling.

The Pennsylvania law is also facing a challenge from the state’s chapter of the American Civil Liberties Union, which claims the law will disenfranchise thousands of voters. Hearings in the case began July 25.

Meanwhile, the state’s Republican lawmakers have already predicted the state would go to Mitt Romney in November’s presidential election. Pennsylvania House Majority Leader Mike Turzai mentioned the law among the other list of accomplishments the state’s Republicans have accomplished.

“Pro-Second Amendment? The Castle Doctrine, it’s done. First pro-life legislation—abortion facility regulations—in 22 years, done. Voter ID, which is going to allow Governor Romney to win the state of Pennsylvania, done,” Turzai said, according to PoliticsPA.
