On November 6, 1860, the six-year-old Republican Party elected its first president. During the tense crisis months that followed  —  the “secession winter” of 1860–61  —  practically all observers believed that Lincoln and the Republicans would begin attacking slavery as soon as they took power.

Democrats in the North blamed the Republican Party for the entire sectional crisis. They accused Republicans of plotting to circumvent the Constitutional prohibition against direct federal attacks on slavery. Republicans would instead allegedly try to squeeze slavery to death indirectly, by abolishing it in the territories and in Washington DC, suppressing it in the high seas, and refusing federal enforcement of the Slave Laws.

The first to succumb to the Republican program of “ultimate extinction,” Democrats charged, would be the border states where slavery was most vulnerable. For Northern Democrats, this is what caused the crisis; the Republicans were to blame for trying to get around the Constitution.
