What ruling was that?
Dred Scott?
Since when did the Supreme Court have veto power over the other two branches of Government?
That is called Judical tyranny.
The Democrats split on that phony ruling as well, hence the election of Lincoln.
So because Lincoln was not going to obey a Supreme Court ruling (like say Jackson?) that gave the South the right to secede?
The territories in question had been open for decades. There were only a handful of blacks enumerated in the census. Lincoln simply wanted his white supremacist Mecca - a lily white west
No, Lincoln wanted slavery to end not grow.
Moreover, free labor did not want to compete against slave labor.
I am sure that you are the exception to that, you would not mind someone bringing in slave labor to compete for your job.
The Confederate Constitution had the Negro race signaled out as the slave race-forever.
So, stop talking about Yankee racism when the South split its own party over keeping one race in slavery.
In fact, Lincoln and the Republicans did obey the DSD, while trying to undo it politically. Of course, that is the essence of American political theory. We are not a nation ruled by an elite tribunal.
More accurately, he wanted to "save the union", regardless of slavery.
