McGrath has touched on a quirk of history; he is correct. By July 9, 1776, Heinrich Miller had made a translation and printed it in his newspaper, the German language "Philadelphischer Staatsboote."
German did not, however, 'nearly get adopted as the primary language'. Many Germans had settled in Pennsylvania, and the language remained important there for more than 100 years. Some small groups still speak it at home and English remains a second language.

Foreign language papers were common during the immigrant years.
In Texas, the German paper printed in New Braunfels was published from the 1850's until the 1950's. When I was at the University of Texas, I used German language primers from schools in the New Braunfels area as a help in learning German, a reading knowledge of which was required for the degree. I still have one of them, with its label "This book is the property of the State of Texas," and the injunction in boldface, "Pupils must not write on or mark any page of this textbook."

There are some 17 Spanish newspapers in the United States, plus English papers that have Spanish sections. Qué' Pasa, in North Carolina, has a 24/7 radio service from seven transmitters covering the State. Several of the papers have online editions.
