One in every eight voting registrations contain significant errors, according to a new report from the Pew Center on the States.
Pew found errors in 24 million registrations. About 1.8 million dead people were still listed as registered, some 2.8 million had active registrations in more than one state, and 12 million registrations had serious enough errors for concern.
Pew researchers blame outdated voter registration systems for the errors.
"Voter registration is the gateway to participating in our democracy, but these antiquated, paper-based systems are plagued with errors and inefficiencies," said David Becker, director of election initiatives at the Pew Center on the States. "These problems waste taxpayer dollars, undermine voter confidence, and fuel partisan disputes over the integrity of our elections."
The report, titled "Inaccurate, Costly, and Inefficient," also found that at least 51 million potential voters are not registered.
