I would not pay too much attention to such crap. The pro-life vermin tried this trick in Maryland in 1992 based on results of a similar poll (the so called question 6 which asked for restriction on repreductive freedom). And they woke up to a very big surprise, as the question was defeated at the polls by the ratio 2:1.
Opinion polls are notoriously misleading - for a number of good reasons, people tend to give "politically correct" or "socially acceptable" answers instead of saying what they really think.
