Augustus Caesar Dodge was a Democratic delegate to the U.S. House of Representatives from Iowa Territory, a U.S. minister to Spain, and one of the first set of United States senators to represent Iowa after it was admitted to the Union as a state. His father, Henry Dodge, served as a U.S. senator from Wisconsin; the two were the first and so far the only father-son pair to serve concurrently in the Senate, which they did from 1848 to 1855.
George Wallace Jones was an American frontiersman, entrepreneur, attorney, and judge, was among the first two United States Senators to represent the state of Iowa after it was admitted to the Union in 1846. A Democrat who was elected before the birth of the Republican Party, Jones served over ten years in the Senate, from December 7, 1848 to March 3, 1859. During the American Civil War, he was arrested by Federal authorities and briefly jailed on suspicion of having pro-Confederate sympathies.
The Territory of Wisconsin was an organized and incorporated territory of the United States that existed from July 3, 1836, until May 29, 1848, when an eastern portion of the territory was admitted to the Union as the State of Wisconsin. Belmont was initially chosen as the capital of the territory. In 1837, the territorial legislature met in Burlington, just north of the Skunk River on the Mississippi, which became part of the Iowa Territory in 1838. In that year, 1838, the territorial capital of Wisconsin was moved to Madison.
The 1860–61 United States House of Representatives elections were held on various dates in various states between August 6, 1860, and October 24, 1861, before or after the first session of the 37th United States Congress convened on July 4, 1861. The number of House seats initially increased to 239 when California was apportioned an extra one, but these elections were affected by the outbreak of the American Civil War and resulted in over 56 vacancies.
The Peace Conference of 1861 was a meeting of 131 leading American politicians in February 1861, at the Willard Hotel in Washington, D.C., on the eve of the American Civil War. The conference's purpose was to avoid, if possible, the secession of the eight slave states from the upper and border South that had not done so as of that date. The seven states that had already seceded did not attend.
Alvin Saunders was a U.S. Senator from Nebraska, as well as the final and longest-serving governor of the Nebraska Territory, a tenure he served during most of the American Civil War.

The 2008 United States elections were held on Tuesday, November 4, 2008, during the war on terror and the onset of the Great Recession. It was a considered a Democratic wave election, with Democratic Senator Barack Obama of Illinois defeating Senator John McCain of Arizona by a wide margin, and the Democrats bolstering their majorities in both chambers of Congress.
The 1862–63 United States Senate elections were held on various dates in various states, occurring during the American Civil War. As these U.S. Senate elections were prior to the ratification of the Seventeenth Amendment in 1913, senators were chosen by state legislatures. Senators were elected over a wide range of time throughout 1862 and 1863, and a seat may have been filled months late or remained vacant due to legislative deadlock. In these elections, terms were up for the senators in Class 1.
