Thousands of citizens have needed intervention from federal judges in the last several weeks in order to vote. Even more remarkably, a few million adult Americans will be denied the right to vote this year. In Ohio, residents who make a minor error filling out personal information will have their votes discarded. In Texas, people have posted photographs to social media showing signs at polling places that claim voters need photo identification. In Wisconsin, some state employees have made it difficult to obtain voter-identification cards, defying a court order.
