What do you propose, gentlemen of the Free-Soil party? Do you propose to better the condition of the slave? Not at all. What then do you propose? You say you are opposed to the expansion of slavery. […] Is the slave to be benefited by it? Not at all. What then do you propose? It is not humanity that influences you in the position which you now occupy before the country. […] It is that you may have an opportunity of cheating us that you want to limit slave territory within circumscribed bounds. It is that you may have a majority in the Congress of the United States and convert the Government into an engine of Northern aggrandizement. It is that your section may grow in power and prosperity upon treasures unjustly taken from the South, like the vampire bloated and gorged with the blood which it has secretly sucked from its victim. You desire to weaken the political power of the Southern states; and why? Because you want, by an unjust system of legislation, to promote the industry of the New England states, at the expense of the people of the South and their industry. Jefferson Davis, 1856 speech in U.S. Senate.
