IMO, a photo ID should be required in order to reduce fraud. It's not hard to get a photo ID, even if you don't need/have a driver's license or passport. In many states, you can get a photo ID card (not a DL) simply by getting a photo taken and filling out some paperwork. If that's too much work for someone, I doubt they're diligent enough in their homework to make an informed decision on a candidate anyway... If they are physically/mentally unable to do this, surely there are people that would help them?
