Someone showed up at a Ted Cruz event in Elkhart, Indiana today with a copy of the Communist Manifesto. According to a reporter for the Texas Tribune, the kid, who looked like he could be a college student, asked Cruz to sign his “economic textbook.”

Video of the encounter published by WSBT22 shows Cruz paused and said, “You know what, I’ll sign it as well.” The college kid replied, “Ah, you have a good sense of humor.” Here is the note Cruz added to the book:

After handing the book back, Cruz turned to the press, “There you go and for the record the note I wrote on the Communist Manifesto is ‘Millions have suffered because of this.’ Turning back to the student he added, “And I note this as the son of a Cuban immigrant whose family has seen first hand just exactly what Communism has rendered. Cruz then shook the young man’s hand and thanked him for coming out to the rally.

Kudos to Cruz for not falling for the prank and handling it well. You can be sure that if he hadn’t noticed what this was and signed it with something anodyne like ‘Thanks for your support!’ the left would have been giddy over it.
