Member states of the Electronic Registration Information Center, or ERIC, partnership share voter registration and identification data to avoid having people registered to vote in multiple states.
There are now only seven Republican-led states among the 25 remaining in the compact.
Many Republican-led states have also tightened voting rules in recent years in what they describe as an effort to prevent fraud.
"It really exposes the hypocrisy of states that are talking the most about voter fraud," Clapman said.
"They're inflating concerns about voter fraud and are also pulling out of and damaging the best tool that states have to detect voter fraud."
