AMUSING, INTERESTING, OUTRAGEOUS, or PROFOUND

There are many instances where people who are indeed citizens may not have proper proof of citizenship, disproportionately among older Americans, college students, poorer Americans, victims of fires, and those who have moved around a lot. Passports are a relatively expensive document. Birth certificates and Social Security cards are fragile paper. Driver's licenses are also not ubiquitous among people who cannot afford a car. Higher bars to be able to vote like this disenfranchise millions of Americans, often historically marginalized racial and ethnic minority communities.

It is easier to prove residency than citizenship, because most people receive physical mail which is enough proof to register to vote in many states. Homeless shelters can also provide proof of residency. And there is very little evidence of undocumented immigrants voting in national elections. It's a Boogeyman because Republicans want to suppress the votes of marginalized groups that disproportionately vote Democrat. Undocumented immigrants tend to do their best to stay away from high risk things like breaking laws and giving the government their information because of the risk of deportation.
