The "donkey-elephant dispute" is a term commonly used by domestic media in the United States when reporting on presidential elections and congressional midterm elections. In 1828, Democrat Jacobson ran for the seventh president of the United States. At that time, his opponents criticized him as a "stupid donkey" and mocked him for advocating "letting the people rule." After Jackson was elected, the nickname "Donkey" was attached to his head. In 1870, the famous cartoonist Thomas Nester published a cartoon of a clumsy donkey in Harper's Weekly to satirize the Democrats who opposed the Civil War at the time. Unexpectedly, the Democratic Party readily accepted it and regarded the stupid donkey as an animal that is both smart and brave. In 1874, Nestor drew another cartoon: a donkey and an elephant pressing on the seesaw. The moral of this cartoon is that the U.S. government has two political parties that take turns in power. When Democrats and Republicans saw this painting, not only did they not find it disobedient, but they also expressed appreciation for it. They explained that donkeys are stubborn and elephants are mature and stable. Since then, "donkey" and "elephant" have become the symbols of the Democratic Party and the Democratic Party. In 1880, the Democratic Party began to use the donkey as the representative animal of the Democratic Party in the presidential election. Later, every election year, supporters of the two parties always liked to hold up "donkey" and "elephant" signs to promote their campaigns. Some enthusiasts even paraded real donkeys and elephants through the streets to enhance their electoral prestige. .
