The votes on two Minnesota Constitutional amendments have tightened with about two-thirds of the state's precincts totaled.

With nearly 66% of the vote counted, the Marriage Amendment — which would limit marriage to one man and one woman — is trailing NO votes, 50.8% to 49.2%.

A second amendment which would require voters to show a government-issued ID at the polls is also losing. With nearly 66% of the precincts counted, the NO votes lead the YES votes 52.3% to 47.7%.

In Minnesota, a blank ballot on an amendment question counts as a NO vote.
