The fear that millions of newly arrived illegal immigrants are swaying federal elections by voting unlawfully has become a recurring theme in debates over immigration.
The idea has so much buy-in that earlier this year, House lawmakers passed the Safeguard American Voter Eligibility (SAVE) Act, which calls for states to "take affirmative steps on an ongoing basis to ensure that only U.S. citizens are registered to vote" in federal elections. Sen. Thom Tillis (R–N.C.), who co-sponsored the Senate version of the SAVE Act, implied that it was a timely—and urgent—attempt to ensure election integrity.
