On the “problem” of noncitizens voting:

«In 2012, then-Florida Gov. Rick Scott ordered state officials to clear the rolls of noncitizen voters ahead of the election.

Florida initially assembled a list of about 180,000 potential noncitizens. With more scrutiny, however, officials whittled the count to about 2,600 names, then 198, then 85. The initial list was rife with errors, even flagging a Brooklyn-born World War II veteran.»

(There’s more examples, for other states, not just Florida.)
