Mark Cuban says he would get rid of both the Republican and Democratic parties if he could do it by waving a 'magic wand'

• Mark Cuban slammed the two-party system during a Bloomberg interview.
• The billionaire said he would get rid of both parties if he could do it by waving a "magic wand."
• Cuban said he'd once consulted his lawyers on filing antitrust actions against both parties.

"Shark Tank" star Mark Cuban isn't a fan of the two-party system.

"You know, parties vote unilaterally, right? They all vote the same despite representing districts or states that are all across the country. That's just insane," Cuban told reporter Olivia Nuzzi in an interview on Bloomberg's "Working Capital."

The interview, which was recorded in March, was released on Thursday. In it, Cuban expressed his misgivings about the US political system and the inherent divisiveness he sees in it.

"The way we vote for our candidates is through a primary system, where you know, a greater percentage of the primary voters lean towards extremes, whether it's right or left," Cuban said.

"And so you have to have candidates, in order to not get primaried, who lean towards those extremes. And that's also the people who give money to those people. That's not the way to pick candidates. It's just wrong."

This situation, Cuban said, has driven him to find ways to shut down both the Republican and Democratic parties.

"If I could wave the magic wand, I'd get rid of the two parties, right?" Cuban told Nuzzi.

"I went and talked to a couple of lawyers actually, and I hadn't talked about this before, 'Like, is there any way we could file any type of antitrust actions against both parties?'" Cuban added.

Cuban says he's holding an open call and asking people with legitimate complaints about the parties to contact him so they can "sue them for antitrust and just try to take them down."

When asked about his open call on Thursday, Cuban told Business Insider that no one's contacted him yet.

"If you find someone with a legit antitrust case against the major parties. I'm interested," he added.

Cuban has often weighed in on political issues. He's stopped short of running for public office himself but has floated the idea of an independent bid several times .

In 2015, Cuban also said he was open to serving as Donald Trump's running mate . But Cuban's views on Trump soon shifted.

"If he lasts four years, I'll be there to kick his ass," Cuban said back in 2017, the year Trump took office as president.

Cuban is now backing Vice President Kamala Harris' campaign. Cuban initially endorsed President Joe Biden before the president dropped out of the race.

"Given it's the system we have right now. I'll vote Harris," Cuban told BI on Thursday.

When Harris introduced Gov. Tim Walz of Minnesota as her running mate, Cuban said the Harris-Walz ticket could be a draw for voters because of their non-Ivy League academic backgrounds .

"People are tired of the ideologues and hate from both parties. They want to vote for normal people they can relate to," Cuban wrote in an X post on August 6.
