benajmin, Texas was the last state to enter the Union as a slave state and it was already an independent republic practicing slavery at the time, and the proponents of slavery found it impossible to find another state to accept slavery, whether in California, Kansas or elsewhere.
There were constant noises about how New Mexico-Arizona was obvious slave state material but somehow actually getting slave owners to move to that area proved impossible. By 1858 a total of 12 slaves lived permanently in that area.
Meanwhile there was every reason to believe that states like Missouri, where immigration from the German states was flourishing, or Delaware, where the practice was extremely limited, would choose to abolish slavery in the near future. Not to mention the 1864 bombshell when Maryland chose to do so, which came as a shock even to many abolitionists.
Certainly any review of the opinions and rhetoric of the time makes clear the abolitionists felt they were winning and the other side did not disagree.
The key point is that the alleged success of slavery in the minority of states still practicing slavery would be irrelevant on the day in the foreseeable future when there would be sufficient free states to pass an amendment outlawing slavery.
