Explanation: When you go to vote for a candidate, the place that you go is called the poll. Last year my polling place changed from a school to a nursing home; every year, though, I go to the poll to vote.
Polar bears live near the north pole, way up north in the Arctic circle (I could talk about the decrease in the population of polar bears but I won’t). This joke is funny because of the play on words with poll and pole.
I wonder if Santa Claus votes at the north poll too?
