2During the 1854 Federal Election, the voters of Sangamon County elected Lincoln to the Illinois General Assembly. Although he was an unwilling candidate for this position at first, passage of the Kansas-Nebraska Act and its effective repeal of the Missouri Compromise had reawakened his passion for politics, and he threw himself into the congressional election campaign in the fall of 1854, crisscrossing Illinois to deliver speeches against the Kansas-Nebraska Act and in support of anti-Nebraska candidates. As the election campaign reached its climax, his name began circulating as a possible nominee for one of the state’s U.S. Senate seats. In November and December 1854, he wrote confidential letters to political allies, seeking support for his candidacy and information about his prospects. Per article three, section seven of the 1848 Illinois Constitution, however, state legislators were ineligible for election to the U.S. Senate. Lincoln’s decision not to accept his General Assembly seat freed him to pursue a seat in the U.S. Senate.
In the special election held on December 23, 1854 to fill his vacancy in the General Assembly, Democrat Jonathan McDaniel triumphed over Whig Norman M. Broadwell by nearly 100 votes.
Ultimately, Lincoln did not win election to the U.S. Senate; the General Assembly selected anti-Nebraska Democrat Lyman Trumbull instead. See the 1854 Federal Election. Stung and disappointed by his loss, Lincoln made no political speeches or public statements for an entire year after his defeat and reinvested his energies in his law practice.
