ST. PAUL, Minn. (AP) - The Minnesota Senate Finance Committee has advanced a voter ID constitutional amendment after discussing the costs of taking such a vote.

The proposed amendment would require voters to show a state-issued photo ID at the polls.

An estimate of local and state costs for taking a vote on the amendment itself came to just over $100,000.

The longer-term costs of the amendment aren't known because it doesn't spell out how photo IDs would be checked in local elections.

The amendment moves to the Senate Rules Committee. The House hasn't acted yet on the companion bill.
