Proponents of voter ID claim it is needed to prevent fraud, while opponents point out that there's not enough fraud for it to be worth the cost.
Note that countries such as Australia, Canada, and New Zealand also didn't require voter ID. First-world countries that do require ID to vote have systems in place to ensure that getting that ID is easy even for poorer people - such as automatically sending the ID to the voter by mail if the government requires you to report your residence or filing out the necessary forms once, before turning 18.
there's no scientific link between race and the ability to go to a DMV once every 10 years
I have seen this constantly claimed, and never reasonably evidenced. It's also hard to believe the kind of American exceptionalism that supposedly causes these problems that everyone else can easily solve, despite an environment that is clearly heavily politically invested in solving it (because that also avoids the appearance of racism).
Meanwhile, American proponents of voter ID can readily find people including among the supposedly discriminated-against groups who will testify to the contrary.
In Canada a drivers license is enough to vote.
