Ahead of an upcoming Supreme Court decision, a new NBC News/Wall Street Journal poll finds that nearly six-in-10 Americans -- 57 percent -- want the court to rule that same-sex couples have a constitutional right to marry.
Thirty-seven percent oppose such ruling.
This finding is essentially unchanged from an April 2015 NBC/WSJ poll, when the split was 58 percent favor/37 percent oppose.
There's a clear difference by party in the current poll: 74 percent of Democrats and 62 percent of independents favor the Supreme Court legalizing gay marriage, versus just 33 percent of Republicans.
The NBC/WSJ poll was conducted June 14-18 of 1,000 adults (nearly 400 via cell phone), and it has an overall margin of error of plus-minus 3.1 percentage points.
