RICHMOND, Va. — Some 6.9 million Americans are registered to vote in two or more states, according to a report obtained by Watchdog.org.

“Our nation’s voter rolls are a mess,” says Catherine Engelbrecht, president of the election-watch group True The Vote.

“Sensible approaches to roll maintenance are fought tooth and nail by radical special interests who can use the duplicity in the system to their advantage,” she said.
