When you created the poll, Doodle sent you an admin link (the manage poll button). The link can be used to modify or delete the poll. You can click the 'more' menu at the top of the page and then 'delete' to delete the poll. 

You can also just ignore a poll you no longer need, Doodle deletes outdated polls from time to time. Please refer to the Policy for additional information.
