It's not free for everyone. The SAVE act will require everyone to reregister to vote with a proof of citizenship.
Not everyone has their birth certificate on hand. Not all women have their marriage license on hand. Not everyone who changed their name has the documents on hand.
Given that the driver's licenses of trans people in Kansas were just rendered null and void seemingly out of nowhere, that's gonna cause a lot of problems for them trying to vote under these laws, wouldn't you agree?
Laws are very clear across the country - don't lie about things when filling out personal data on a diver's license form. . .which includes what your BIOLOGICAL sex is.
