Perhaps the OP is confusing this with the "multiple choice" option, which gives the poll check boxes rather than radio buttons. But even with this option, it is only possible to vote for several options at once. It is never possible to go back and change the options voted for.
Would you mind deleting the "not sure yet" option as this totally blows away any usefulness this poll may actually have?
