Wendell Phillips of Boston, speaking on the inherent purpose of his (and Lincoln’s) party: “The Republican party is in no sense a national party. It is a party of the North, organized against the South.”

Is it any wonder that some Southern States seceded after Lincoln's "party of the North" came into power in 1860. 

In an 1845 essay titled "No Union with Slaveholders", he argued for DISUNION and on the eve of the war he defended the Confederate States' right to secede saying: 

"A large body of people, sufficient to make a nation, have come to the conclusion that they will have a government of a certain form. Who denies them the right? Standing with the principles of '76 behind us, who can deny them the right? . . . I maintain on the principles of '76 that Abraham Lincoln has no right to a soldier in Fort Sumter. . . . You can never make such a war popular. . . . The North never will endorse such a war."

(But the North did endorse Lincoln's war when he maneuvered the South into firing on Sumter by his contrived resupply attempt; making the South appear to be the aggressor).
