Karl Marx; the great enemy of human freedom. - Harry V. Jaffa

The possibilities for slavery expansion were almost endless. Douglas would have done these things, but he couldn't subscribe to the slave code. And on that basis, they seceded, and that split the Democratic Party, and that elected Abraham Lincoln.

Now it's absolutely true, and I agree with Professor DiLorenzo, that the Republican Party could never have been successful without the support of the tariff interests involved. The Free Soil Party and the Liberty Party were anti-slavery parties, which were, you might say, pure in their principles, but they had no chance of being successful on a national basis. It was the addition of the tariff interests that gave the Republicans the ability to carry their anti-slavery program into action. And it’s in that light, I think, that you have to look at the whole question of the tariffs.

Three years later in the contest for Kansas, the administration headed by James Buchanan tried to railroad through a constitution called the Lecompton Constitution, which would have made Kansas a slave state, but on the basis of a phony vote. Douglas stuck to his popular-sovereignty doctrine, which meant that the people of the territory, in a fair vote, would decide for or against slavery. That was the way in which he replaced the Missouri Compromise restriction. It opened slavery, but it said that the decision in each territory would be made by the people in that territory on the basis of their preferences.
