Nikki Haley utterly botched an answer about the cause of the Civil War at the worst possible time for her campaign

• Presidential candidates face plenty of questions on the campaign trail, some easier than others.
• On Wednesday, for example, GOP candidate Nikki Haley was asked about the cause of the Civil War.
• After failing to answer, "slavery," she's facing heat at the worst possible time in her campaign.

Many factors ultimately culminated in eleven southern US states seceding from the rest of the country in 1861 and instigating the Civil War, but surely, everyone can agree that '"slavery" was at the top of the list, or at the very least, enough of a reason to mention, right?

The short, unfortunate answer, is no.
