Stephen Colbert and the entire staff of The Colbert Report will make the trip from New York City through New Jersey to Philadelphia for a week’s worth of shows (April 14-17) right before the Pennsylvania Democratic primary. It’s the first road trip for the show. "The Colbert Report: Dorito’s Spicy Sweet Pennsylvania Primary Coverage
From Chili-Delphia – The City Of Brotherly Crunch!" will be taped at
the 900-seat The Annenberg Center for the Performing Art’s Zellerbach
Theatre on the campus of the University of Pennsylvania.

And the money quote from the Comedy Central press release: "The road to the Democratic nomination goes through Pennsylvania and I
intend to make my show the decisive pothole on that road!" Colbert said.
"Plus, it’s just across the river from Camden, New Jersey!"
