I personally dont think there is any thing with with asking people to provide their Drivers liscense or their state ID card at the voting booths. Most banks in my area ask for your ID or DL when you open a checking account. Most banks in my area ask for your ID/DL when you cash a check. Most stores in my area ask for your ID/DL when you right them a check. Most stores in my area ask for your ID/DL when you use a credit card or debit card. The police in my area always ask you for your ID/DL when they feel you are breaking the law or just generally want to know what you doing.
So I fail to see how it is some right wing conspiricy to fix voting results by asking for these things when you go to vote. After all if your to scared to go get a DL/ID then your probally doing some thing illeagel to begin with an the last time i checked criminals didnt have the right to vote any way.
