In the United States of America, only 7 states require photo identification, according to this map. U.S. Sen. David Vitter is looking to change that.

Sen. Vitter has offered an amendment to the Senate budget resolution to require a valid government-issued photo ID to vote in a federal election. "Republicans, Democrats, conservatives and liberals should all agree that ensuring election integrity is vital to maintain an honest and healthy representative democracy," says Vitter.

Vitter points out that photo IDs are required for many day to day activities: driving, opening a bank account, getting on a plane or entering a federal building. He believes it should be no different for a citizen voting in a federal election:

A federal election should not be devalued by a fraudulent vote cast by someone else.

Earlier this week, Sen. Vitter announced he would block block President Obama's nomination of Thomas Perez as Secretary of the Labor Department. Vitter says he will do so until the Department of Justice responds to his 2011 letter related to Perez's "spotty enforcement" of the National Voter Registration Act in Louisiana.

“Thomas Perez’s record should be met with great suspicion by my colleagues...but Louisianians most certainly should have cause for concern about this nomination,” said Vitter. “Perez was greatly involved in the DOJ’s partisan full court press to pressure Louisiana’s Secretary of State to only enforce one side of the law – the side that specifically benefits the politics of the president and his administration at the expense of identity security of each and every Louisianian on the voter rolls.”

Vitter says Perez's Civil Rights Division has repeatedly sued states attempting to ensure election integrity including Louisiana, Texas and South Carolina.
