I've noticed bad math with the multi-select polls and figured it was something due to the total number of people voting vs. the number of votes which was how the % totals usually ended up over 100%.
This is the first time I've seen a regular poll be odd. The % total is way short of 100 and if you look (or at least at the time I posted this) the bars did not represent the actual vote values correctly. The bottom option is in the lead but has a vote count lower than the one that really should be.
Just a heads up. I have a screenshot if it somehow corrects itself.
