NBC News: “The dominant political story heading into the Nov. 4 midterm elections isn’t control of the U.S. Senate, or President Obama’s approval ratings, or the party that captures the most governor’s mansions across the nation. Instead, it’s that this country – long known for its combative politics, especially before an election – is more divided today than it has been in decades. And it’s likely to remain that way for the foreseeable future.”
