That's technically correct--if you show up at a place and time where the state accepts applications for an ID and submit your application with all required supporting documentation the state will not be able to charge a fee to process you application and give you your ID.

But there is no limit on what it might cost you to (1) obtain the required supporting documentation and (2) go to where you can submit your application at a time when they are accepting applications.

For older people and for poorer people these can be a significant problem. The fact is the for nearly all of its existence the US has not required much ID, meaning it is very hard to transition to such a requirement without disenfranchising many citizens. So far I don't think any proposal for stronger ID requirements has tried to address this.

Many states already have required ID for voting, and indeed a state ID card can be obtained from the DMV for a nominal cost, probably free in need-based cases.

Don’t assume that. There’s a MAGA bro movement advocating against direct election of senators.

The Supreme Court will do backflips to make the determination that they’re paid to make.
