This should be more than disconcerting; it’s a situation that could get dangerous. As the Princeton political scientist Mark Beissinger has shown, separatist movements can take hold around contempt for incumbents and the status quo even when protesters have no ideology in common.
The United States hardly seems to be on the verge of fracture, and the small secession movements in a handful of American states today represent a tiny percentage of those polled by Reuters. But any country where 60 million people declare themselves to be sincerely aggrieved — especially one that is fractious by nature — is a country inviting either the sophistry of a demagogue or a serious movement for reform.
