Senate Democrats nixed a proposal to ask voters whether people should provide photo identification before casting their ballot.
A Senate committee rejected the proposal Wednesday on party-line vote. House Republicans previously passed the measure.
The measure died on the same day Minnesota lawmakers referred a measure to voters in November asking whether photo ID should be required at the polls.
Democrats say voter impersonation is rare and that requiring photo ID at the polls could lead to voter suppression among minorities, the elderly and the homeless. Republicans say the requirement does not decrease voter turnout and that it's needed to prevent voter fraud.
Colorado Republicans tried a similar proposal last year but it wouldn't have required the voters' approval. That bill also failed in the Senate.
