Transcribed Image Text:An American study published in a recent year claimed to find evidence of voting by nanditizens. The conclusion was based largely on a survey several years prior in which approadmately 38,000 registered voters were asked both whether they voted and whether they were diens. A total of 309 of those surveyed reported being noncitizens,
