Is green a red and blue construct? Put another way, is there a political partisan divide over the environment?

That's a particularly interesting question, no doubt more so in recent years as the country seems to have drifted farther and farther apart because of our political beliefs. To that point, a reader reached out the other day to say our stories shouldn't be negative on the Trump Administration because the national parks are going to need the help of all of us - Democrats, Republicans, Independents, and everything in-between - to survive.

But are environmental issues highly partisan? For the Traveler's purpose, we'll define "environmental issues" as those focused on public lands, wildlife, clean air, clean water, and of course the national parks.

To help us try to answer that question, our guest today is Caleb Scoville, a professor at Tufts University who has received an Andrew Carnegie fellowship to explore that question.
