Most notably, the poll shows the Marriage Protection Amendment winning among Democrats as well:

Marriage Amendment proponents appear to be ahead in North Carolina, according to polling done by the Civitas Institute on April 30 to May 2.

Support for the proposed amendment to the state constitution that would give the current definition of marriage additional legal protection remains strong as One-Stop Absentee Voting enters its final days. Applying survey results to current voter turnout trends and anticipated election day voting would project the amendment winning by no less than a 16 percentage-point margin.

A survey of partisan primary voters shows the amendment winning among Democrats by a slim 48-to-44 percent margin and among Republicans by a 78-to-15 percent margin. The largest supporters of the amendment among Democratic voters are black voters (38 percent of the sample), who support the amendment by a 2-to-1 margin -- 63 to 30 percent. Self-identified conservative Democrats (23 percent of the sample) support the amendment by an 82-to-13 percent margin. -- ABC WWAY 3
