Enhance Polling functionality

We notice that polling options show as check boxes, even if you can only select one choice. Normally, check boxes denote multiple options can be checked and radio buttons show only one can be selected. Could you make it radio buttons if only one option can be selected?

Also, it would be nice if you only show the results of the poll AFTER someone selects their choice(s). Showing the results may sway the voter when making their selection.
