"I had an insurmountable object to overcome in that presidential bid and that was the wisdom and the inherent good judgment of the American people," Thompson told John Stewart Thursday on Comedy Central's "The Daily Show."
"So it worked out for everybody," Thompson said after the audience's laughter and applause subsided.
The former "Law & Order" actor was on Stewart's show to promote his new book, "Teaching the Pig to Dance."
