Heritage Foundation on 2020, number of non-citizen voters:

If I'm viewing this correctly, there were 16 instances of non-citizens being charged with voter registration or voting between 2020 and 2024, and if my quick review is correct, only four of them actually voted.
https://electionfraud.heritage.org/searchAccording to the 5th Circuit in that 2016 decision I cited earlier, the Texas voter ID law (that was overturned) would have precluded as many as 600,000 American citizens from voting in TX. Is that number high? Probably. But let's say it was 1% of that: 6,000 American citizens denied the right to vote. That's just in Texas, but let's make that nationwide as a result of many states adopting these laws. That to stop those four people from voting--the 12 more who illegally registered (and were caught without a voter ID law)--don't even figure in. But what if they did? 16 people across the United States prevented from illegally voting. 6,000 citizens stripped of their legal right to vote. Does that make for a better democracy? I don't think so. Apparently many of you do. Cool. As noted, your side has won this argument.
Fearless: why die on the hill of protecting citizens' right to vote? That seems self explanatory.
But I'll indulge y'all a little more. On the cynical side (which is at least partly true) why does the Democratic party die on this hill? Because it thinks most of these people will vote for Democrats--but also, probably more importantly, because it wants to hold the mantle of protecting minority voter rights, which Democrats believe will attract more votes from minority voters, even those not directly impacted.
Why do civil rights organizations die on this hill? Because their stated mission is to protect individual civil rights, and the right to vote is
the core right in a democracy.
Believe it or not, some people, regardless of party, believe in protecting individuals' voting rights, regardless of how that may or may not help a particular party. I like to think that describes me.
