More than half of North Carolina residents now support legal recognition of same-sex couples, and more than one-quarter believe they should have full marriage rights.
An Elon University survey released Monday found that only 35 percent of respondents opposed all legal recognition, down from 44 percent when the question was asked two years ago.
The poll says 29 percent support civil unions or partnerships for same-sex couples but not full marriage rights. About 28 percent of people support marriage rights.
About two dozen Republican senators in North Carolina have proposed a constitutional amendment to ban gay unions.
The poll was conducted last week and surveyed 467 North Carolina residents. It has a margin of error of plus or minus 4.6 percentage points.
