Wikipedia is set up so that only people who look for these articles/pictures will know about voting procedures. So of course if there is a vote, the majority would probably be overall positive unless serious canvassing went on to let people who care about the other side know about it so it evens out. Canvassing is set up to prevent this--I believe it's actually a way of biasing the community to serve only the community, and not the readers. Because the readers are--the world. Telling people about the topic is just like how any election goes. I guess unless you are in some sort of fake election where people are led to believe that their votes actually count.
