Two Pennsylvania lawmakers appeared on Fox News Sunday to discuss the state's controversial voter ID law.

The law requires voters to show a specific state-issued photo ID card at the polls. It was sponsored by Pennsylvania House Majority Leader Mike Turzai (R-28th District).

"Keep in mind this legislation is really just about presenting voter identification. Which you do when you're buying Sudafed at a drugstore, or going to a place to buy beer, or to a gym," Turzai said on Fox News.

Senator Daylin Leach (D-17th District), on the other hand, is one of the law's most vocal opponents, saying it disenfranchises voters.

"The reason this law was passed is because there are a number of people, easily identified demographic groups, who don't tend to have ID's. They don't tend to have driver's licenses. People who are poor, people who live in the inner cities, and elderly people, all groups that tend to vote Democratic in very large numbers," Leach said.

The ID law was upheld in state court last month and later overturned by the Supreme Court of Pennsylvania. The Supreme Court instructed the judge who originally upheld it to take another crack at this case and determine whether the state will actually make it difficult for people who don't have the proper identification to get it. The case will go back to state court on Tuesday.
