I could see most of those happening in Hillary's dream landslide, but South Carolina and Mississippi? There's no way the abysmal D organization in those states could ever beat Trump.
Those states are more liable to flip than Texas because they were closer in 2012 than Texas and Mississippi is closer than Texas.
They might be closer, but I don't think that the elections being slightly closer necessarily means there's a better chance of that state flipping. In order for the state to flip, there has to be some reasonable explanation for why voters that picked one party might now pick a different party. I think Texas is unlikely, but at least there's an argument for it like some people mentioned. I don't see where the potential for flipping is in SC and MS.
