“Millions have suffered because of this.”

At a campaign event Thursday in Elkhart, Indiana, a young man tried to trick Ted Cruz into signing a copy of “The Communist Manifesto,” but the Texas senator wasn’t about to let that guy get away with it.

Instead of just affixing his autograph to the front page, Cruz signed his name to a message that read: “Millions have suffered because of this.”

Boom.

I have a feeling that the guy pushing this book in Cruz’s face walked away feeling probably a little less-than-pleased with himself.

Let this be a lesson to millennials who are not the sharpest knives in the drawer: Don’t mess with a career litigator who destroyed everyone as a debater at Princeton.
