Note: Only the poll’s creator, a group owner, or a group moderator with the Edit Archive permission can delete polls.

You can use either of these methods to delete a poll:

• Open the poll message on its own page, click or tap More at the lower right, and select Delete Poll from the popup menu. Then, in the Verify Delete confirmation popup, click or tap Yes.
• View the list of polls, click or tap the down arrow next to the one you want to delete, and select Delete Poll from the dropdown menu. Then, in the Verify Delete confirmation popup, click  or tap Yes.
