HARRISBURG, Pa. (August 15, 2012)--Commonwealth Court Judge Robert Simpson refused Wednesday to grant an injunction that would have halted Pennsylvania’s new voter identification law, which requires each voter to show a valid photo ID.

Opponents are expected to file a prompt appeal to the state Supreme Court as the Nov. 6 presidential election looms.

The law is the subject of a furious debate over voting rights.

Those challenging it include some who say they'll be unable to vote.

Democrats say the law will make it harder for the elderly, minorities, poor and young adults to vote, and is designed to help Republican challenger Mitt Romney beat Democratic President Barack Obama.

Republicans who control the Legislature and the governor's office say they think it'll prevent voter fraud.
