state audits and data compiled by groups across the political spectrum have found no indication that noncitizens are voting in large numbers.
Basically, rules imposing additional requirements on voter registration prevent vastly more citizens from voting than noncitizens, since the latter aren’t trying to vote.
Nobody cares. If we could make it free and easy enough it would stop being useful at suppressing the vote and Republicans would lose all interest and Democrats already don’t care.
Anything which requires action in all 50 states and the government giving up a source of revenue and overhauling complicated systems couldn’t be completed this century. While we are at it though I would like a hardware security key handed out with your ID as a second form of ID and required for any sort of large purchase like a car, or opening a line of credit.
