See a Washington Post article about two people working side by side in the same factory holding diametrically opposing views about U.S. politics. The article's author, Eli Saslow, does a reasonably balanced job of describing our political separation, except he does say that things are definitely getting better in their Ohio town. So, my judgment: mostly balanced, not completely.
Saslow's description of the way the Arm & Hammer employees have decided not to talk politics in order to maintain civility at work reminds me of the way we behave at big family gatherings. We simply cannot talk politics without hating each other, and almost everybody "gets it."
