First things first, I don’t doubt it is a bad thing, considering who supports it and who doesn’t.
But my question is what exactly is the issue and what is the current and proposed voting process when it comes to IDs?
Here in my EU country, you have to show some version of a government ID, be it an ID card, drivers license or passport. And we don’t have to pre-register to vote.
Brennan Center has done multiple rounds of polling on it, there is no single source, just a wide group of agreement in data from voting rights and legal groups like the SLPC.
The problem is that when it comes up in documented cases like when Connecticut rolled back their voter ID law due to disruptions in municipal votes, it’s a small sample that doesn’t reflect the entire state, just that local area. When it comes to larger data sets, you run into voter privacy protection laws that no one wants to risk violating on either side. So you can’t even collect information. Which is why we have exit polling and similar sampling methods.
