In addition to the %, would it not help to show how many have voted? A poll can show 100% in favour of an option but if only one person has voted, it's hardly valid is it?
or of course if one person votes 20 times, as I did on a previous poll. I wasn't trying to skew it, I was just trying to see how the results were going, which you can't unless you vote. So I may be personally responsible for the Law section (and for torpedoing the Celebrity section),
