Making voting harder also disproportionately affects the more marginalized populations.
And the more marginalized populations tend to vote for Democrats.
If you are one of the people that can just call off work on a whim, then taking a day off, or a part of a day off, to go to vote is easy. If you own your own car, then traveling to the polling places is easy.
If you work in a job where calling off is frowned upon, whether it’s because of asshole bosses or legitimate work that needs to be done and can’t be postponed, then getting out of work to go vote may be difficult. If you also rely on public transportation, that can make it even more so.
Then you are going to wait in line for hours before you can vote.
Compare that to a less marginalized area, where people have cars, they have jobs they can call off on a whim, and they never wait in a line.
In short, no it does not affect all voters equally, not at all.
