Your contention and their Opinion doesn't prove error.

"I believe..." --
President Lincoln
"It may well be questioned..."
This is all just commentary, not data.
"I believe..." and "It may well..." is nothing. Here is the data
After South Carolina seceded, (1/9/1861—2/1/1861) six other states seceded. Mississippi (1/9) on a vote of 85-15; Florida (1/10) 62-7; Alabama (1/11) on a vote of 61-39; Georgia (1/19) 208-89; Louisiana (1/26) 113-17; Texas (2/1) voting 166-8.
So, in reality, this comment ->Lincoln went to war to prevent the formation of a government by a clear majority of the southern people<-is in fact supported by historical voting records.
Only ONE HUNDRED people lived in Mississippi? Wow.
I've got to check Nevins, but you are going to be very embarrassed.
