Cory Booker, mayor of Newark, N.J., and Democratic U.S. Senate candidate, left the Garden State on Wednesday night to practice his stand-up stump speech in Philadelphia.

Booker did the right things beforehand, telling his 1.4 million Twitter followers @CoryBooker, “Politicians trying 2B funny. Recipe 4 disaster?”¬†And making a joke up top in his set at “Stu Bykofsky’s Candidates Comedy Night” that his mere appearance there would be a mistake.

But he was there, and cameras were there from the Wall Street Journal, to capture it all.

Was it a disaster? Roll the clip!
