I have to dissent here. That's not 'mob' rule. That's simply a majority exercising their will. That's precisely why the President should NOT be elected by an electoral college. I mean that's just pure democracy in action. And it's a big example of why a lot of people in blue areas are pissed off. Exhibit A: McConnell fails to hold a vote on Obama's pick for SCOTUS in 2016. Trump gets elected electorally and not with a popular majority (only one Republican has managed that since 1988). 3 justices later, a string of politically motivated rulings has now ended right to an abortion, increased religious encroachment in public schools, dismantled part of the Voting Rights Act, and now appears poised to hand state legislatures the right to override the will of their own citizens during national elections and draw their own gerrymandered maps without any interference from Courts.
Putting aside the flaws of the left for a moment, that right there is what fear against 'mob rule' gets you. The cultural conservatives are in the minority on vast array of topics from LGBT rights, abortion, health care, and many others. Such people are threatened with complete irrelevance in a decade or less. So now they are doubling down and trying to entrench their power before it slips away. Before my generation and the one below mine becomes the largest voting bloc.
The state of this country has many causes and what I just stated is just one element of it. But 'states rights' is often another thought stopping cliche used to justify just about anything- kind of like "You just got to have faith.", (to discount arguments against religion) "God works in mysterious ways." (to discount the problem of evil), "If you are poor then you don't work hard enough." (to discount the unfairness of our economic system), and "Those who can't do, teach" (to discount the wisdom of those with an education, who often push against these kinds of mindsets). People who do not seek truth and instead want to follow a worldview that is comfortable to them use these to stop conversation on uncomfortable topics.
