When Republicans won a plurality in the House in 1858, every significant bill they passed fell before southern votes in the Senate or a Presidential veto. The Federal Government reached a stalemate. Bitter hostility between Republicans and Southern members prevailed on the floor of Congress.
To prevent a 1860 sucession, you would have to prevent the OTL 1860 result where this Plurality became a majority.
It was this great increase of Rupublican Office holders at both ?Federal and State levels that
triggered the Walkout.
Even if you can hold it together in 1860, I don't see how you can prevent, an 1862, or 1864, Walkout. You don't make it to 1868.
But the WI says 1868....... .So ...........
Between 1800 & 1830 most of the Available [non land or slave] Capital in the South went into expanding the Transportation system --IE Canals.
When the canal companies went bankrucpt in the 1830's they took this Capital; with them.
[Most of those canals are part of the Inter coastal Waterways today]
By the late 1850's this was in the past, and the South had a Pool of Capital to work with again.
Most of this was again in trasportation [ie Railroads] not in large companies like JP Morgan, but smaller local companies,
But some was going into Industries.
There are problems [involing Feeding, Clothing, Housing] with a Slave operated Factory inside a city, that you don't have, in a Rural setting.
By 1860 a lot of these problem had been solved, and the first Slave Factories were starting to show some Profits.
Given another 8 years, there would have been a lot more development, in the south.
As president James Buchanan, believed that using the power of the Federal Government to prevent Sucession was Unconsitutional
In Buchanan's Message to Congress (December 3, 1860), he denied the legal right of states to secede but held that the Federal Government legally could not prevent them. He hoped for compromise, but secessionist leaders did not want it.
On January 5, Buchanan sent a civilian steamer Star of the West to carry reinforcements and supplies to Fort Sumter. On January 9, 1861, South Carolina state batteries opened fire on the Star of the West, which returned to New York. Paralyzed, Buchanan made no further moves to prepare for war.
With Buchanan unwilling to act, President Elect Lincoln did.
Ordering the Federal troops in Baltimore [following the Assianation attemp] to occupy Annaopolis to prevent Sucession.
And ordering the Evacuation, of Norfolk and Hampton Road, and the burning of the Facilities there.
Now I don't see Steward with a second term given the compromising in 1862, And Debate/Positions on Mexico.
So some one else in 1864. ?Any Ideas for Whom?
Almost anyone else would react different than Buchannan.
So .. Dec 1868 South Carolina Suceeds, Followed by six other slave states seceded, the Confederacy was formed, all arsenals and forts in the seceded states were lost (except Fort Sumter and two remote ones), and a fourth of all federal soldiers surrendered to Texas troops. The government decided to hold on to Fort Sumter, which was located in Charleston harbor, the most visible spot in the Confederacy. On January 5, President ???????? sent a civilian steamer Star of the West to carry reinforcements and supplies to Fort Sumter. On January 9, 1869, South Carolina state batteries opened fire on the Star of the West, which returned to New York.
President ??????????? Adresses Congress asking for funds and Men to put down the rebellion.
When The incoming President takes Office in March, the war is two Months old.
