Mark Cuban on Wednesday said that Donald Trump Donald John TrumpObama calls on Senate not to fill Ginsburg's vacancy until after election Planned Parenthood: 'The fate of our rights' depends on Ginsburg replacement Progressive group to spend M in ad campaign on Supreme Court vacancy MORE should avoid getting lost in policy details when fighting Hillary Clinton Hillary Diane Rodham ClintonWhat Senate Republicans have said about election-year Supreme Court vacancies Bipartisan praise pours in after Ginsburg's death Trump carries on with rally, unaware of Ginsburg's death MORE in the general election this November.

“He’s got to have the ‘Seinfeld’ campaign, a campaign about nothing,” Cuban said on Fox Business Network’s “Cavuto Coast to Coast.”

“My guess is he will not touch on any policy details whatsoever because there’s no upside for him,” he added of the presumptive GOP presidential nominee.

“If Hillary tries to force him into policy issues, then it won’t work. He’ll just talk around her and go another way. He’s just going to blame [President] Obama. Whatever it is, it’s Obama’s fault.”

Cuban said that Trump had benefited from years of establishment Republicans achieving little while vilifying Clinton.

“I think he looked at how the Republicans treated Hillary — ‘she’s a criminal, she’s a liar,’ whatever else you want to call her, every name in the book,’” the businessman said of the Democratic presidential front-runner.

Cuban added that critics are misguided by accusing Trump of sexism for attacking Clinton’s public record.

“Donald and I have had our battles,” he said. "People talk about Donald being sexist. There’s nothing he’s said about a woman that he hasn’t said to me. You know, he’s called me ‘ugly,’ he’s called me ‘short off the tee,’ he’s called me all these ridiculous things. That’s just how he combats it.

“I think what a lot of people fail to realize is, look at every condemnation of Hillary Clinton to date. They’ve done such a great job on the right with just putting down Hillary so that it’s anybody but Hillary."
