The bill backed by Republican Secretary of State Tre Hargett advanced Thursday. The House needs to vote on Senate changes.
The legislation creates class A misdemeanors if, knowingly or intentionally, groups pay workers based on quotas; or enroll 100-plus voters and shirk state training or fail to ship completed forms within 10 days of registration drives or by the deadline.
Groups submitting 100-plus incomplete registrations over a year could be fined.
Opponents worry the bill will hinder Tennessee’s already-low voter participation.
Hargett’s office has lamented Tennessee Black Voter Project’s submission of about 10,000 Shelby County registrations on last year’s deadline, many filled out incorrectly.
