And for those reasons, he’s out.

Mt. Lebanon native Mark Cuban, who’s fond of using that line when he declines to invest in a pitch on “SharkTank,” has decided he will not mount a third-party campaign for president in 2024.

“No. My family would disown me,” Cuban wrote in an email to NBC News.

In 2019, Cuban, the billionaire owner of the Dallas Mavericks, considered running for president in 2020, also as a third-party candidate.

Then, as now, Cuban said it was his family’s “no” vote that kept him from running, CNN reported. Despite a pollster finding he could get around 77% of independent votes and take some from Donald Trump and Joe Biden, he felt his chances weren’t good enough.

NBC reported that Cuban confirmed he had spoken with “NoLabels,” a bipartisan group founded by former U.S. Sen. Joe Lieberman, which is working to get a third party presidential candidate on ballots in all 50 states.

Cuban said the group’s effort to form a 2024 ticket is “very important.”

“I like that they are trying a new path. I think the two-party system is broken,” Cuban told NBC.

No Labels plans to pick a Democrat and a Republican to run as a ticket at an April convention in Dallas.
