Mark Cuban: I'm 'Actively Considering' Running For President in 2020

He ain't running for President, he's floated this idea before.

Billionaire investor and entrepreneur Mark Cuban told CNBC's "Fast Money" on Tuesday that he's "actively considering" a run for the presidency.

However, he said there's a 90 percent chance he won't run, citing his wife's displeasure with the idea.

"Based off what's happening in the White House, based off what's happening in the country and the world, we need better leadership. And I think I could do a better job," he said. "But there's a lot more to it than just thinking you can do a better job and so, I'm not ready to make the commitment."

A lot can happen in the next three years. If a candidate emerged who could do a better job than him, Cuban said he would support that person.

"It's not my all-time dream to be president of the United States," he said.
