"If the bill is enacted and if it survives legal challenges, New York City would become the largest jurisdiction in the United States to allow noncitizen voting." There are others, then. Which, and why?

And digressing, why did the USA as a country not do this from the start? The founders said "no taxation without representation", why was the choice made to tax people without representation?

Flip side: citizen votes diluted by non-citizen votes. I would not expect this to hold up to a legal challenge
