The bill passed 19-5 along party lines, with many Democrats refusing to vote. Some later said the GOP would not add their votes following the chaos.

The legislation, which proponents say will prevent people from voting illegally, would give Wisconsin arguably the most restrictive voter identification law in the country. According to the Legislative Fiscal Bureau, it could cost more than $5.7 million to implement.

Under the bill, a voter would have to present a driver’s license, a state ID, a passport, a military ID, naturalization papers or a tribal ID. College students could vote with a school ID as long as it has their signature and an expiration date within two years of the card’s issuance. University of Wisconsin IDs currently do not meet that criteria and would have to be updated to comply before students could use them to vote.

Nursing or retirement home residents, stalking victims and anyone who objects to having his or her photograph taken for religious reasons would be exempt. Anyone who forgets to bring an ID to the polls would be allowed to cast a provisional ballot, but would have to show an ID to the local election clerk by the Friday after the election to have the ballot count.
