Since its debut six years ago, the popularity of “Pawn Stars” – a reality show about a little Las Vegas pawn shop – has exploded worldwide and resulted in more than 400 episodes. Earlier this year, the show’s star, Rick Harrison, announced his support for Republican presidential candidate Marco Rubio, who is riding high after a strong debate performance in Colorado this week. In an exclusive interview with CNN, Harrison discusses why he chose Rubio, his thoughts on Donald Trump and Hillary Clinton, and his hatred of political correctness. This interview has been edited and condensed. CNN: There are more than a dozen Republican presidential candidates. Why did you endorse Marco Rubio and how did you get to know him? RH: I got invited to a political thing in town and we got to talking. … I was deeply impressed. It was the first time I sat down with a politician that long and it wasn’t “the party, the party, the party.” All he was talking about was people. Quite frankly, I’ve never had a politician talk like that. His dad was a bartender at a bowling alley and his mom was a maid at a casino here in town. When someone mentions living paycheck to paycheck, he goes, “Yeah, I was raised that way.” I think if you have a leader, you need someone who has experienced what people are experiencing. CNN: Have you been involved with Republican politics before? RH: I suddenly became famous and I was the one willing to throw my career away to endorse a Republican. When you endorse a Republican, everyone sort of frowns on you. I don’t know why, but hey. CNN: Have you experienced that? RH: To a degree, yeah. There have been some endorsements that didn’t happen. CNN: What do you think about Donald Trump? RH: I’ve never met him, I’m sure he’s a nice guy. I don’t think he’s going to relate to me or anybody else in here because when he grew up and asked his parents, “Can we get that?” He never once in his life heard from his parents, “We can’t afford that, son.” CNN: What do you think of Hillary Clinton? Do you think she was a good negotiator? RH: I can’t really think of anything she actually did. You have the Ukraine situation, which I could go on and on about. You have the Middle East falling apart. I think she was a very bad negotiator. CNN: Do you ever fear that as a public figure, you could say something that would hurt you or the show? RH: The PC thing, it’s gone over the top. … It’s not a perfect world we live in. You can’t raise kids that way and then just throw them out in the world because it’s not a perfect world. CNN: Do you fear you could lose the show? RH: It does worry me to a degree. You get these massive liberal PC police, they don’t see the law of unintended consequences. You have some cities that are saying that if you have a man who feels like he’s a woman, he can use the women’s restroom. I guarantee you that will be taken advantage of by some very bad men who want to go into a bathroom where there’s young ladies. That will happen if you pass a law like that. It’s not a perfect world. You’ll never make it a perfect world.
