Abraham Lincoln to Elihu B. Washburne, 29 January 18591
Hon. E. B. Washburne.My dear Sir
I have just received your brother's speech sent me by yourself–2 I had read it before; and you will oblige me by presenting him with my respects, and tell^ing^ him I doubly thank him for making it— first, because the points are so just and well put; and next, because it is so well timed– We needed, from some one who can get the public attention, just such a speech just at this time–3 His objection to the Oregon constitution because it excludes free negroes, is the only thing I wish he had omitted–4
Your friend as everA. Lincoln

3Israel Washburn Jr. delivered the referenced speech in the U.S. House of Representatives on January 10, 1859. Washburn dedicated his speech to defending the Republican Party, criticizing the Democratic Party, and justifying the Republican opposition to slavery and its extension beyond the American South. Washburn juxtaposed the defining principles of the two parties--democracy for the Republicans and aristocracy for the Democrats. Washburn accused the Democrats of desiring an aristocracy that denies the “equal right of all men” and “divides mankind into two classes—a governing and priviledged class, and a governed and disabled class”. “A practical and authoritative exposition” of Democratic principles, Washburn argued, was found in the pro-slavery Lecompton Constitution, which enshrine property rights, and therefore slavery, as higher than any values written in the Declaration of Independence or the U.S. Constitution. To make this point, he quoted the same provision within the Lecompton Constitution multiple times, which read “The right of property is before and higher than any constitutional sanction; and the right of an owner of a slave to such slave and its increase, is the same, and as inviolable, as the right of the owner of any property whatsoever.”

4Although the Republican Party was formed to prevent the expansion of slavery in the United States with a goal to see its eventual end, members of the party were deeply divided on how to achieve that goal and how aggressively to pursue it. Lincoln was more cautious than some others within the party, such as Washburn, and was anxious to keep the party united on its goals despite differences on policy.
A test of party unity came in the winter of 1858-1859 with the admission of Oregon as a state. Delegates from the Oregon Territory met in a state constitutional convention on August 17, 1857. Democrats dominated the convention, and the state constitution adopted on September 18, 1857 included racial exclusion clauses for free blacks, mulattos, and Chinese immigrants. Article one, section thirty-five, in particular, prohibited the residence of free blacks and mulattoes in the state. Article eighteen set November 9, 1857 as the date for a special election for acceptance or rejection of the constitution and gave voters the right to decide for or against the constitution, slavery, and free blacks. Oregon voters voted down slavery, but approved the constitution and exclusion of free blacks. Congress took up a bill for statehood, but progress sputtered over questions of insufficient population, discrimination against Chinese immigrants, and the prohibition of free blacks. The latter issue became grounds for strong objection. Washburn was among those opposed to the exclusion clause because it violated Republican principles. The bill for statehood was still pending when Washburn made his speech on January 10, 1859. Washburn voted against the constitution on the final vote of February 12, 1859, but it Congress approved the constitution without amendment. Oregon became a state on February 14, 1859. The Fourteenth Amendment abrogated the restrictions on free black and mulattos, but Oregon voters did not vote to remove the exclusion clause from the state constitution until 1926.
