From Garden State Equality:

By 63% to 31%, New Jersey voters say they’d be fine with the state legislature upgrading civil unions to marriage equality.

By 72% to 21%, New Jersey voters say state legislators would be in no electoral danger if they enacted marriage equality.

By 61% to 29%, New Jersey voters say they expect the state to enact marriage equality within just a couple of years.

Zogby asked the baseline question – do you favor marriage equality versus civil unions – in two ways. Results are 48% to 45% for marriage equality in one question, 48% to 30% in another.

It's interesting to think about how that 48% who support same sex marriage changes to 63% when it just asks if voters would be fine with it. It's an area of public policy polling that's hard to accurately gather information about, the degree to which people actually care about these issues.
