You think he wanted to replace the American voters to overcome them, out of patriotism?
Yes, though he never would have thought of it in those terms. He would have thought of it more that he was in the greatest American tradition of accepting immigrants. Note that he sometimes would quote the text on the base of the Statue of Liberty.
He was a bit of an idealist. He also wanted to shut down the Federal Reserve, as an example of his idealism.
