Many blacks though, particularly in the South, focused more on land ownership and education as the key to liberation. As slavery began to seem politically untenable, an array of Northern Democrats successively announced their support for the amendment, including Representative James Brooks, Senator Reverdy Johnson, and the powerful New York political machine known as Tammany Hall. President Lincoln had had concerns that the Emancipation Proclamation of 1863 might be reversed or found invalid by the judiciary after the war. He saw constitutional amendment as a more permanent solution. He had remained outwardly neutral on the amendment because he considered it politically too dangerous. Nonetheless, Lincoln's 1864 election platform resolved to abolish slavery by constitutional amendment.

Republicans in Congress claimed a mandate for abolition, having gained in the elections for Senate and House. The 1864 Democratic vice-presidential nominee, Representative George H.
