Ah. More lies and/or ignorance. Lovely. Let's ask someone who's actually researched this, shall we?
"Critics of [voter ID] laws (myself included) have doubted both their necessity and their ability to keep elections honest. The only type of fraud that a strict photo ID rule would actually prevent is voter impersonation fraud (I go to the polls pretending to be you), and, in fact, voter impersonation fraud is exceedingly rare. In Indiana, where the Republican-dominated legislature passed one of the first new ID laws in 2005 (on a straight party-line vote), there had been no known instances of voter impersonation in the state’s history. In Texas, a strict ID law was enacted last year, although the 2008 and 2010 elections gave rise to only five formal complaints about voter impersonation (out of 13 million votes cast). “There are more UFO and Bigfoot sightings than documented cases of voter impersonation,” quipped one Texas Democrat. Close inspection of the RNLA’s inventory of election fraud, moreover, has found it to be flawed and misleading; most election experts believe that the greatest threat to election integrity comes from absentee ballots—a threat that would not be addressed by the current laws.
As importantly, the burdens placed on prospective voters by these ID requirements are not trivial. Men and women who already possess driver’s licenses or passports, of course, will be unaffected. (So too will those in Texas who have permits to carry concealed weapons—since those permits meet the ID requirement.) But citizens who lack such documents will now be obliged to assemble various other pieces of paper (birth certificates, naturalization forms, proof of residence, etc.) and make their way (presumably without a car) to a government office that can issue an official photo ID. Who are these men and women? Studies indicate that they are disproportionately young or elderly, poor, black, and Hispanic; demographically, they are more likely than not to vote Democratic. (In states covered by the Voting Rights Act, such as Texas and South Carolina, the photo ID laws are being challenged by the Department of Justice on the grounds that they disproportionately affect minorities.) The number of people potentially affected is considerable: the Texas secretary of state, for example, estimates that at least 600,000 already registered voters do not possess the documents to cast ballots in November. New York University’s respected Brennan Center for Justice has estimated that a total of more than five million people may lack the requisite identification documents in states that have passed new ID laws." -http://harvardmagazine.com/2012/07/voter-suppression-returns
So, in a nutshell - Voter ID laws only impact the least likely possible type of voter fraud (voter impersonation), do nothing to address the more likely (but still extremely rare) problem of absentee ballot fraud (the type specifically mentioned in the article in the OP), and disproportionately impact Democratic voters.
Yeah. Clearly justice in action.
