The final pitch by opponents of Amendment One:
PPP's final poll (pdf) finds that Amendment One is likely to pass with the "yes" percentage "somewhere in the 57-59% range." Voter ignorance is a big part of the problem:
In some sense North Carolinians are voting against their own beliefs. 53% of voters in the state support either gay marriage or civil unions, yet a majority also support the amendment that would ban both. The reason for that disconnect is even with just 24 hours until election day only 46% of voters realize the proposal bans both gay marriage and civil unions. Those informed voters oppose the amendment by a 61-37 margin but there may not be enough time left to get the rest of the electorate up to speed.
