Polarization in Washington, and around the country, has been building for years, but it doesn't take a political scientist to know that it has gotten significantly more heated and divided.

"We now, more than ever, I think, live in two divided camps — left vs. right," Berry said. "It's more than we differ from them, we have strong differences from them. It's more that that other side is evil, and for some people, that evil is hard for them to get beyond."
Lou Murray, a Trump supporter, says the partisan fireworks come from the president's enemies.
