Voter ID is often touted as an important part of election security, but when you look at the threat model of elections it just doesn't do much. Think about how you would try to cheat at an election. The common methods are things like ballot stuffing, throwing out votes, discouraging people from voting, etc. Examples include spreading disinformation about what day voting is happening, seizing ballot boxes and replacing them with forged ballots that favor your candidate, or calling in bomb threats to polling places. These are not prevented by voter ID requirements.

The only thing voter ID prevents is voter impersonation. It prevents you from finding someone else's name and polling place, going there, pretending to be that person, and submitting a vote on their behalf. But that threat doesn't really scale. Even if you assume no one at the polling places notice you coming to vote over and over under different names, a single person could probably only do this a few dozen times on election day. To scale that you would need more people; and every person you add to the scheme increases the odds of someone slipping up or getting caught. But the real issue is if any of the people you are impersonating try to vote! While election officials don't record what people voted for, they do record who voted, and the ballot counting process will automatically note that people voted multiple times. So you would have to figure out some way to gather a database of a large number of people you know aren't going to vote, and get a bunch of people to turn up at a bunch of polling places under those names. It's just not practical to do, when elections are decided by thousands or tens of thousands of votes.

The devil is in the details. I don't trust that the groups drafting Voter ID legislation are doing so in good faith. For example, North Dakota passed a voter ID law years ago. It stated that you needed a valid state-issued ID that included a street address. Sounds fine, right? The problem is that most homes on Native American reservations don't actually have street addresses. Tribal members use P.O. boxes for mail, and that P.O. box is on their driver's licenses. This was brought up when the law was proposed, but it passed anyway. The Spirit Lake Nation and the Standing Rock Sioux tribes had to sue in federal court. They were eventually successful, but it took years, and in the meantime the 2018 midterms were held with many Native Americans literally unable to vote.
