Yes, there are people who wan't to prevent large blocks of people from voting. If you're going to deny that you can stop reading now.
FACT: Voter ID Laws disproportionately effect poor and urban voters (who are more likely to vote Democratic), they are designed to do that and that is what they do. It's not about preventing voter fraud, it's about preventing votes from certain demographics. That is why after passing a new voter ID law the Pennsylvania House Majority Leader Mike Turzai (R) said, "Voter ID is gonna allow Governor Romney to win the state of Pennsylvania".
This is how it works, poor urban voters are less likely to have drivers licences or other form of accepted government ID. They are also less likely to have the documentation needed to easily obtain these forms of ID and since it cost money to obtain certified copies of whatever documentation they need the voter ends up not voting. This isn't some stuff I'm just making up, this it how and why it's done. There is also a precedent in law that has said that a requirement to purchase an ID from the government to be able to vote amounts to a Poll Tax and Poll Taxes are illegal in the US. Voter ID Laws have nothing to do with preventing voter fraud, if voter fraud was rampant you could probably find me the names of 10 people that were convicted of voter fraud but you can't because there aren't, it is all a ruse to prevent voting.
If the Republitards were willing to do anything other than spend all their time getting Obama out of office than maybe they wouldn't be a party in shambles on it way to becoming the Whig party of the 21st Century.
