Research suggests up to 34% of voting-age women don't have documents proving citizenship with their current legal name.

A bill introduced by a House Republican requiring voters to provide documentary proof of citizenship when they register to vote has triggered alarm bells among voting and civil rights organizations. The big picture: The Safeguard American Voter Eligibility (SAVE) Act aims to restrict noncitizen voting — which is exceptionally rare and illegal.

Although the bill may be aimed at undocumented immigrants, married women, young voters, and voters of color may get caught in the crossfire. A new bill introduced in Congress last month aims to require proof of citizenship to register to vote—which could make an already-complicated registration process harder for millions of Americans.
