Yancey was a leader of State Rights men but never a leader in the Democratic party. Once, in 1848, when all were angry on account of the opposition on the Mexican question, Yancey was called to the front in the Democratic state convention. He offered resolutions, which were adopted,[9] to the effect (1) that the people of a territory could not prevent the holding of slaves before the formation of a state constitution, and that Congress had no power whatever to restrict slavery in the territories; (2) that those who held the opposite opinion were not Democrats, and that the Democratic party of Alabama would not support for President any candidate who held such views. The delegates to the National Democratic Convention at Baltimore were instructed to withdraw if the Alabama resolutions were rejected. By a vote of two hundred and sixteen to thirty-six they were rejected; yet none of the delegates except Yancey withdrew. Refusing to support Cass for the presidency because he believed in "squatter sovereignty," Yancey was again ostracized by the Democratic leaders.[10] Now the State Rights men became more aggressive, for they said this was the time to settle the slavery question, before it was too late. The North, it was thought, would not be averse to separation from the South. The Whigs began to advance non-intervention theories, and but for the death of President Taylor, who adhered to the free-soil Whigs, political parties in Alabama would probably have broken up in 1850 and fused into one on the slavery question.
