Quote Of The Day, 1892 Division

I was looking through a book of quotations and turning to the page marked immigration, I found this one:

We heartily approve all legitimate efforts to prevent the United States from being used as the dumping ground for the known criminals and professional paupers of Europe.

Where`s that from? It`s from the Democratic Party Platform of 1892. Why was the Democratic Party opposed to this, since even in 1892 they saw themselves as the party of the common man? Well, in 1892, they saw themselves as the party of the common American man.
