MI HB4128

Prohibits city and township clerks from canceling voter registrations solely based on an elector's failure to vote.

Requires the Secretary of State to send forwardable mail within 90 days to all registered electors who have not voted since the 2000 general November election, including a postage-prepaid return card and notice explaining their registration status.

Directs clerks to compare signatures on returned cards to the qualified voter file and mark registration records as "challenged" if signatures do not match.

Marks registration records as "challenged" if the mailed notice is returned as undeliverable, and authorizes the Secretary of State to cancel such registrations if the elector does not vote or engage in voting-related activity by the first business day after the second general November election following the notice date.

Requires electors with challenged registrations to either respond to the notice, vote, or engage in voting-related activity (such as requesting an absent voter ballot or updating registration) to maintain their voter registration status.
