"I don't care what his actual positions are," Cuban wrote, according to Business Insider
. "I don't care if he says the wrong thing. He says what's on his mind. He gives honest answers rather than prepared answers. This is more important than anything any candidate has done in years."
Cuban, who said he voted for Obama in 2008, said he appreciates Trump's attitude and has little concern for his policies.
"I don't care what his actual positions are," Cuban wrote. "I don't care if he says the wrong thing. He says what's on his mind. He gives honest answers rather than prepared answers. This is more important than anything any candidate has done in years."
Cuban says Trump's willingness to withstand the scrutiny that comes with running for political office was admirable.
"Up until Trump announced his candidacy, the conventional wisdom was that you had to be a professional politician in order to run," Cuban wrote. "You had to have a background that was politically scrubbed. In other words, smart people who didn't live perfect lives could never run."
People who feared that the media would focus too much on their private lives would not want to run, Cuban said.
"The Donald is changing all of that. He has changed the game and for that he deserves a lot of credit," the basketball owner said.
Cuban said later Tuesday he did not yet know if he was voting for Trump, but said the way Trump is campaigning benefits voters in the long run.
"I don't agree with much of what he says, but I certainly know where he stands," he said. "More importantly at no points do I feel that he is playing to the base."
Cuban, who has said his politics lean libertarian,
said Trump is revolutionizing Republican politics.
"Politics and in particular Republican politics are such a mess that every comment that comes out of a candidates mouth seems like it was sanitized by consultants in order to appease those that will vote in Republican primaries - except for Trump."
