ST. PAUL  — Minnesota voters are steps away from seeing a photo ID constitutional amendment on the ballot. The full Senate passed the amendment Friday in a 36-30 vote. The House passed the amendment Tuesday.

Debate focused on the system of provisional balloting that the amendment would set up. Provisional ballots could be cast by those who register without ID on election day, but wouldn’t count unless voters returned to confirm their identity.

Democrats said this would be costly and time consuming and could lead to many uncounted votes.

Lawmakers widely supported one amendment to the bill that expands the ID definition to a photo ID “or equivalent,” to provide for future ID technology.
