How many of those 12-15% are actually unable to get an ID as opposed to "can't be bothered/don't need it"?
An ID requirement would get some of those to get one - if they wanted to vote.
And how does the voter turnout look for those groups anyway?
The only people who might be impacted negatively by ID requirement are those unable (for whatever reason? Why can't there be an easy way to get an ID in the first place?) and actually wanting to vote.
I don't know about those groups specifically, but overall turnout is typically around 60% for presidential elections and 40% for midterm elections, for every election since at least 2000.
