These polls are useless as there is no debate over a codified constitutional right. Additionally, is this really a precedent you would want to set? I'm pretty sure everyone was unhappy when gay marriage was doing poorly in the polls (and at the ballot box, hello California!).
It doesn't matter what the people think, the people don't determine constitutional rights.
