A current example is states invalidating all Trans people’s IDs during a primary election. That’s happening right now.
Also - getting an ID is expensive and time consuming in the US. The cliche of spending 4 hours in line at the DMV to get a license even though you made an appointment ahead of time isn’t an exaggeration, and applies to getting an ID as well. The reality is most people won’t spend the time and money to do it just so they can vote every 2 or 4 years - especially people who can’t afford to take a day off work and travel to do it.
But people will do it so they can drive their car every day - so people with IDs are more likely to have more money.
And for people who have driver’s licenses that fall on hard times it’s also a problem, because they stop paying for insurance (invalidates driver’s license), lose their car (keeps them from paying for insurance or renewing license), or even lose their home (address change invalidates license). These are not people who can take a day to go pay to vote. And that’s exactly what they’d be doing, because the new ID card they’d be buying would strictly be for voting. Aside from the cost of the ID, when I updated my DL in June I had to travel 80 miles round trip, and the process took about 7 hours - and I had a car to speed things up.
So it’s effectively pay-to-vote system that only applies to poor people. People with money can vote for free through “motor voter” registration by checking a box when getting or renewing their driver’s license.

Jokes on them. I make above median income and I’ll never be able to afford kids.
