You can poll people/the general public on just about any issue and the answers are going to differ massively depending on framing effects. In the end, it's hardly better than just flipping a coin.
Even if public opinion is unified, if they want something to happen, they are just going to ignore the public and do it anyway. Like the recent cases of data enter projects where they just ignore the public voting against them. Democracy’s weakness it it requires people to follow the rules, but if nobody voluntarily follows the rules, then we don’t really have one.
