This bill matters because it changes the balance between making voter registration easy and ensuring election security. If this bill becomes law and states adopt the new requirement, it could mean a more secure voter roll by potentially preventing non-citizens from registering to vote, as it adds an extra layer of verification. Voters might feel more confident that only eligible citizens are participating in elections.

However, it could also make it harder for some eligible citizens to register to vote, particularly those who lack easy access to citizenship documents, such as elderly individuals, people experiencing homelessness, or those who have lost important papers. If the bill doesn't pass, the current system of self-attestation for mail-in voter registration would remain, keeping the process potentially simpler but without the added proof-of-citizenship requirement.
