Politics and Prose is located on Connecticut Avenue in Northwest D.C.
Across the industry, a lot of bookstores have been struggling recently or have been closing. Graham and Muscatine are not deterred.
"Well we believe very much in the future of independent bookstores, and Politics and Prose has been a leader in the industry," Graham says.
Muscatine says the bookstore is unique in how it provides a space for civil discourse.
"I think as the world gets more fast-paced, and everything becomes more instantaneous, people actually crave and long for that even more," she says.
They have new ideas, including how to keep Politics and Prose up-to-date technologically. But, they say, preserving the things that make the bookstore "great" is key.
And they say they're prepared for the challenge.
"We really think that in one way or another, our careers have been about the intersection of writing and ideas, and that's really what the store is about also," Muscatine says.
