NILES' NATIONAL REGISTER, Baltimore, Sept. 12, 1846  Page 3 has a report from Illinois on election returns, which notes: "...7th district, Cartwright (loco.), 4829; Lincoln, (whig) 6340 (elected...".
History tells us that n 1843 Abraham Lincoln sought the Whig nomination for Illinois' 7th district seat in the U.S. House of Representatives. He was defeated by John J. Hardin though he prevailed with the party in limiting Hardin to one term. Lincoln not only pulled off his strategy of gaining the nomination in 1846 but also won the election. Lincoln was 37 years old.
This is followed by: "Mormon Troubles" which takes over a full column reporting on the on-going Mormon War with the anti-Mormons vs. the Mormons in Illinois, as seen in the photos.
There are 6 pages taken up with much reporting on the Mexican War with subheads including; "Battles of the Rio Grande" "The Army of Occupation" "Ohio Volunteers" "The Bombardment of Fort Brown" and more.
Sixteen pages, 8 3/4 by 12 inches, a crease through the pages, very nice condition.

As noted in Wikipedia, this title: "...(was) one of the most widely-circulated magazines in the United States...Devoted primarily to politics...considered an important source for the history of the period."
