One vote per public IP for this poll. If tied, I will choose between the tied entries. With no votes, no winner is selected.

To limit duplicates, your IP is processed into a poll-specific keyed hash; the IP itself is not stored by the poll. The hash is scheduled for deletion 7 days after closing; deletion is asynchronous. Shared connections share one vote. No voting cookies.
