What animal is the emblem of the U.S. Democratic political party?

The United States Democratic party is recognized by the symbol of a donkey, and the Republican party is represented by an elephant. The Democratic donkey was first associated in 1828 with Democrat Andrew Jackson’s campaign. His opponents had called him a donkey, so Jackson decided to use the image of the strong-willed donkey on his posters. Later, famous cartoonist Thomas Nast used the donkey in newspaper cartoons and made the symbol famous.
