J.H. in Lake Forest, CA, writes: The origin of this verse is unknown; it’s been around since at least 1956, though in slightly different form:

The election is over; the results well known;
The will of the people is clearly shown.
Let’s forget our troubles and show by our deeds
That we’ll give our leader all the help that he needs.
So let’s all get together and let bitterness pass;
I’ll hug your elephant and you kiss my donkey.
