A Mark Cuban-Donald Trump presidential match-up? Not even close. Hillary Clinton wouldn’t stand a chance, either.

That’s the political prognostication of none other than Cuban himself, who, like Trump, is a visible and controversial American billionaire. Trump and Clinton are actually running for the White House; Cuban tells CNBC he gets asked about doing so “every day.” The Dallas Mavericks owner didn’t say he’s getting into the race, but here’s his view about how two match-ups would shake out:

“If I ran as a Dem, I know I could beat Hillary Clinton. And if it was me vs. Trump, I would crush him. No doubt about it,” he said.

Cuban’s comments came in an email exchange with CNBC, published early Monday. He outlines issues he’d focus on if he did run, like income inequality, college debt, overly complex taxes and cybersecurity.

In a phone interview with CNBC that aired later Monday, Cuban said he wasn’t interested in running for the White House in 2016 — but didn’t explicitly rule out a future run. “I think I can have a bigger impact right now in doing a lot of the other things that I’m doing,” he said, including investing in small businesses and talking to students. “I just don’t have the temperament, at least not at this point, to be a politician,” he said.

Cuban also said Clinton had “kind of blown it.” Watch:

Should Cuban actually run, he wouldn’t be the only well-known businessman who’s interested in the political process. Security-software pioneer John McAfee — formerly a fugitive from authorities in Belize — is running for the White House.

“I’d rather have a Trump, or I’d rather have a man on the street who has no knowledge of government,” Politico quotes McAfee saying.

CNBC notes Cuban, like Trump, isn’t a stranger to controversy. He’s been fined repeatedly by the NBA for his criticism of referees during Mavericks games.

And Cuban was famously involved in a long battle with the Securities and Exchange Commission — a battle he ultimately won. The SEC sued Cuban in civil court, alleging he traded on nonpublic information when he sold his investment in Canadian search company Mamma.com in June 2004. A federal jury found him not guilty of insider trading in October 2013.
