From The AP:
Republican presidential candidate Nikki Haley was asked Wednesday by a New Hampshire voter about the reason for the Civil War, and she didn’t mention slavery in her response — leading the voter to say he was “astonished” by her omission.
Asked during a town hall in Berlin, New Hampshire, what she believed had caused the war — the first shots of which were fired in her home state of South Carolina — Haley talked about the role of government, replying that it involved “the freedoms of what people could and couldn’t do.”
And from Politico:
Nikki Haley declined to say that slavery was a cause of the Civil War on Wednesday evening, placing the blame, instead, on the role of government.
The former UN Ambassador and South Carolina governor, who has seen her star rise in the first-in-the-nation primary state, was appearing at a town hall event in Berlin, New Hampshire, when a voter asked her to identify the cause of the war.
“I think the cause of the Civil War was basically how government was going to run,” she responded. “The freedoms and what people could and couldn’t do.
Here's the thing. The AP states that the first shots of the Civil War were fired in South Carolina. That would be April 12, 1861 - The Battle of Fort Sumter. The issue had been boiling for sometime and we only need to look at South Carolina's own Declaration of Secession to see why:
The ends for which the Constitution was framed are declared by itself to be "to form a more perfect union, establish justice, insure domestic tranquility, provide for the common defence, promote the general welfare, and secure the blessings of liberty to ourselves and our posterity."
These ends it endeavored to accomplish by a Federal Government, in which each State was recognized as an equal, and had separate control over its own institutions. The right of property in slaves was recognized by giving to free persons distinct political rights, by giving them the right to represent, and burthening them with direct taxes for three-fifths of their slaves; by authorizing the importation of slaves for twenty years; and by stipulating for the rendition of fugitives from labor.
We affirm that these ends for which this Government was instituted have been defeated, and the Government itself has been made destructive of them by the action of the non-slaveholding States. Those States have assume the right of deciding upon the propriety of our domestic institutions; and have denied the rights of property established in fifteen of the States and recognized by the Constitution; they have denounced as sinful the institution of slavery; they have permitted open establishment among them of societies, whose avowed object is to disturb the peace and to eloign the property of the citizens of other States. They have encouraged and assisted thousands of our slaves to leave their homes; and those who remain, have been incited by emissaries, books and pictures to servile insurrection.
They were upset about this:
The General Government, as the common agent, passed laws to carry into effect these stipulations of the States. For many years these laws were executed. But an increasing hostility on the part of the non-slaveholding States to the institution of slavery, has led to a disregard of their obligations, and the laws of the General Government have ceased to effect the objects of the Constitution. The States of Maine, New Hampshire, Vermont, Massachusetts, Connecticut, Rhode Island, New York, Pennsylvania, Illinois, Indiana, Michigan, Wisconsin and Iowa, have enacted laws which either nullify the Acts of Congress or render useless any attempt to execute them. In many of these States the fugitive is discharged from service or labor claimed, and in none of them has the State Government complied with the stipulation made in the Constitution. The State of New Jersey, at an early day, passed a law in conformity with her constitutional obligation; but the current of anti-slavery feeling has led her more recently to enact laws which render inoperative the remedies provided by her own law and by the laws of Congress. In the State of New York even the right of transit for a slave has been denied by her tribunals; and the States of Ohio and Iowa have refused to surrender to justice fugitives charged with murder, and with inciting servile insurrection in the State of Virginia. Thus the constituted compact has been deliberately broken and disregarded by the non-slaveholding States, and the consequence follows that South Carolina is released from her obligation.
Here fugitives=enslaved humans who escaped slavery and were seeking shelter in another state.
South Carolina said that those states had a constitutional obligation to return those "fugitives" and since they did not, " the constituted compact has been deliberately broken" and South Carolina could secede.
It was about protecting a state's right to enslave human beings.
And this is supposed to be the GOP's "acceptable" alternative to Orange Jesus?
