Former GOP presidential candidate Ted Cruz once went on “The Late Show” and asked Stephen Colbert if he could “humanize” him. Colbert was explaining to an audience at New York mag’s Vulture Festival on Saturday that audiences can “smell a prepared answer” from a politician. “I don’t want to betray my guest because there’s what happens on-camera and off-camera, but I guess it’s okay because I don’t think [Ted Cruz] understood what he was asking,” the 53-year-old host said.
