You've missed that creating birth certificates and other documents is "not legal". Getting around the issues takes lawsuits and other time consuming resources. And, I have agreed to take those that need just transportation, and there are regular drivers that do regularly take people to "town". For most of them their property is registered, it is the photo id that is the problem, and the requirements are not working for some. My precinct works already, there is zero fraud without a photo id. And 3/4 of the registered voters are Republican.
But the real question is why should anyone have to .... show me the fraud! Of course it would be nice if it were in significant number to have changed more than just a precinct, but I'll settle for documentation of fraud and how a photo id will prevent that particular fraud.
