I have yet to figure this out. Can you see the results without voting? I was prompted to ask this by BrazenCanadian's poll in the wedding section about wedding costs. I would like to see the results, but don't want to mess up the results by voting since I have never been married.
I have also come across this dilemma when I create a poll myself. I have had to vote and just remember what I voted for so I can see the true results.
