The second of two Constitutional Amendments that will be on the ballot this November is the Minnesota Voter Identification Amendment.
Currently, in Minnesota, registered voters do not need ID of any kind to vote. Voters arrive at their polling place, and if they are on the list of registered voters, they may vote. Unregistered voters may bring ID and register to vote on the day of the election, or they can be "vouched for" by a signed oath from a registered voter.
The Minnesota Voter Identification Amendment seeks to change the constitution to require that all voters show a photo identification before voting. The amendment also requires that the state of Minnesota must provide free ID to those who do not have a photo ID. It also requires that voters without a photo ID can cast a provisional ballot, which will be counted if the voter can subsequently provide a photo ID. Vouching will no longer be permitted.
A Yes vote will require all voters to have ID to vote. Supporters argue that this will improve election integrity and reduce voter fraud.
A No vote will not change the law, and the voting process will not change. Supporters of a No vote argue that voter fraud is very rare. Changing the rules to require ID will make it harder for many people to vote, specifically seniors and minority groups, both who are less likely to have ID. They disagree with any legislation which makes it harder for citizens to exercise their right to vote.
