Tens of thousands of eligible voters in at least six swing states have been removed from the rolls or have been blocked from registering in ways that appear to violate federal law, according to a review of state records and Social Security data by The New York Times.
The screening or trimming of voter registration lists in the six states — Colorado, Indiana, Ohio, Michigan, Nevada and North Carolina — could also result in problems at the polls on Election Day: people who have been removed from the rolls are likely to show up only to be challenged by political party officials or election workers, resulting in confusion, long lines and heated tempers.
