Because not everyone is capable of getting an ID. For one, they're not free, so requiring one is effectively a voting tax, preventing the poorest of our community members from having a say in our government.

Two, even if they were free monetarily, they're not free to get in terms of time. If you're working 16 hours a day at 2 jobs for example, when are you supposed to take time to go to the DMV to get an ID or license? This is particularly hard for, again, poorer people who have to work multiple jobs to stay afloat.

Three, there really is no problem that requiring an ID at a polling station solves. Of the BILLIONS of votes in the Heritage Foundation's (a VERY conservative thinktank, the one Trump tapped for most of his judicial nominations) database recording voter fraud events, they have a little more than 1000 instances of SUSPECTED voter fraud. That's about 0.0001% of votes cast are suspected to be fraudulent by the people trying to push the policy to correct the problem.

Meanwhile, these laws prevent more people from voting legally each election than have ever been suspected of voting fraudulantly since we have been keeping records. They are doing research to find the specific forms of IDs the people who vote against them tend to have or not have, and explicitly targetting them to ensure as few votes against them are allowed to be cast. It is an inheirently undemocratic solution to a problem which the proponents of the policy openly state does not exist.

I voted for a couple decades by just saying my name and having it crossed off the list, and back then the rate of voter fraud was basically zero just like it is after adding a barrier that keeps some people from voting.

Voter ID laws only exist to make it harder for poor people and minorities to vote.

Shouldn't the logic be the other way? Why would you need to?

I've never had to do this and there's never been an issue so it seems like a solution in search of a problem to me.

IDs varies greatly in the US. They are not federal, they are not free, and the difficulty of obtaining the documents to get your ID often disproportionately affects poor people. In the US we banned poll taxes for many of the reasons people oppose these voter ID laws.

its a method of voter suppression , and only every gop used it thats why. its a burdensome fee, and not many people, mainly AA people can get one right away. likely you will have to show 2 or more proofs of CITIZENSHIP, which can be difficult for most people and LICENSES dont count. valid passports, certificate of naturalization, birth certificate is actually quite difficult to get. for passports only some places have the option to apply one, USPS and then you have to book appointments too, which can be booked weeks to months in advance.
