Dallas Mavericks owner Mark Cuban says he cast his ballot early. And, unsurprisingly, he voted for Hillary Clinton.

"Yeah I already voted. For Hillary Clinton, who do you think?" Cuban told NBC 5's Newy Scruggs on his NBC Sports Radio show.

Then he added a little voter-fraud joke to stir up the Donald Trump supporters:

"I voted 17 times just for Donald Trump fans."

Cuban has been a thorn in Trump's side for quite a while in this election cycle. And he kept the criticism coming in his interview with Scruggs.

"I think he'd be the worst president ever," Cuban said. "Temperament, lack of knowledge, lack of wisdom, lack of anything for that matter. He doesn't know what's he's going to do. I think he'd be a puppet. The interesting thing to me about Donald is when he reads his speeches -- when you see teleprompter Trump -- it's like he's reading them for the first time. It's obvious that he didn't write them. It's obvious that a lot of these positions, he might agree with them but he didn't create them. He didn't get into the substance of them. To me that's horrible.

"The only certainty about the presidency is the uncertainty. And if you don't do the work to have the knowledge, if you don't have the wisdom to deal with the information, you're not going to be a good president. And I know people say he'll just hire great people, but anybody who's run any business that has a lot of varied opinions ... imagine his military advisers. Five of them have five different ideas about what to do in a dangerous situation. If you don't understand what's going on, you can't make the right decision. And I don't think he does the work to be in a position to make those right decisions, no matter how good advisers he has.

"There are people I know who work for Trump that aren't going to vote for him and are terrified he might get elected. That's how bad he is.

"As far as Secretary Clinton, she's smart, she does the work. She understands policy. If you quizzed her or asked her about any of her positions, she's going to be able to give in-depth answers like we saw in the debates. She understands the issues when it comes to the balance of power in the world. She knows the world leaders and she understands them. She may not agree with them, she may be adversarial with some of them. But she's not going to say something flippant or stupid. So I that makes her the safer play, that makes the world safer. Whereas with Donald Trump, I think there 100 percent certainty that he's going to say something stupid that upsets somebody and creates a critical situation for all of us."

"And look, with Hillary Clinton, there are a lot of people who have a lot of really bad feelings about her. She's done a horrible job of addressing all the propaganda against her. But when I did my research, I just didn't see any there there."

Cuban also said he doesn't see the FBI's reopened probe of Clinton's private email server use swaying the election.

"There's nothing that she's said or nothing that anybody's said that makes me think, 'Oh no. This is something unique,'" Cuban said. "If you think that Hillary Clinton is the worst person in the universe, you're still going to think that. If you're uncertain, it shouldn't have any effect on what you think about the two candidates."

And if you think boycotting Cuban and his Mavericks will make him shut up about politics, he's got some bad news for you.

"When it's all said and done, I'd rather lose every penny than have Trump as president," Cuban said. "Because I care more about the future of my family and my children than I do about my pocketbook. And if that means we play to empty arenas, I'm down with that. What could be more important than my kids? The idea of my kids growing up in a Trump presidency? I know the guy. And there's just no chance. I could go on for days.

"Maybe I pick up some fans, maybe I lose some fans. I don't know. I've heard it from both. I've had people say, 'There's no way I can support you. I won't go to another Mavs game.' And I've had people say, 'You know what, we're buying Mavs tickets.' What I've heard more of than anything: Are you going to be this way once the election's over? And the answer's no. ... Come Nov. 9, it's all Mavs all the time. And Shark Tank in there too."

So once the election's over, could Cuban see himself and Trump burying the hatchet and taking in a Mavericks game together?

"Nah. I don't see it," Cuban said. "Win lose or draw with him. He just went in a different direction. I always liked to pick on him. When he wasn't running for president, it was just fun to mess with him. If we won a big game, he would reach out and say something positive. When he was winning the primaries, I would reach out and say something positive. And we'd still mess with each other. But now, this is the real deal. This is the most powerful position in the world, and I don't know that he takes it nearly as seriously as he should."

The Dallas Mavericks will not be staying at any Trump hotels this season.

Owner Mark Cuban told me this on my NBC Sports Radio show Tuesday saying, "No. We did stay previously and quite a few team did reach out and asked what we were doing and they said that they were staying at the Trump hotels and we chose not to anymore longer and actually it wasn't my suggestion, it was multiple other people's suggestion inside the organization."
