It's an interesting poll topic, but it has a flaw in its methodology. It assumes that every voter thinks that the current span is the
maximum that copyright terms should ever be: that is, it assumes that every voter wants a span of liftetime of the creator plus 70 years, or some amount
less than that.
That's certainly not what Disney wants, and there's no way from these poll results to assess if anyone here feels that a longer span is the way to go (indeed, if one choice is copyright should be abolished, another should be that copyright is permanent and never expires).
I'm not advocating for any particular position here, but my mother the statistician would spank me if I didn't point out the inherent bias in the way the question is phrased.
