Do you know the difference between a democracy and a constitutional republic? Georgetown University law professor Randy Barnett wants to clear up any confusion.

Barnett, director of Georgetown’s Center for the Constitution, wrote the book “Our Republican Constitution” to explain what the founders really meant by “We the People” in the U.S. Constitution.

During a recent visit to The Heritage Foundation, we caught up with Barnett to talk about the book and why he’s pessimistic about the outlook of the U.S. Supreme Court following Antonin Scalia’s death and President Barack Obama’s nomination of Merrick Garland.

“There’s a lot at stake with the next Supreme Court justice, but I can already tell you, I believe that fight has been lost,” Barnett said. “We have to decide how we’re going to survive under a court that is hostile to how we think.”
