One of my favorite images of anti-Asian racism, this less than subtle image from either the late 1870s or early 1880s lays it out there for all of us to see. The Workingman's Party was the dominate force in California politics during the years leading up to Chinese exclusion. Their entire platform consisted of saving California for the white man by ending Chinese immigration. That they became such a political threat to both parties helped lead to the passage of the Chinese Exclusion Act in 1882.
In this get out the vote image, you see the white man kicking the Chinese guy in the butt, with his queue extending all the way over the Pacific back to China, where he is fleeing.
