Mark Cuban, the billionaire who spent the final stretch of the 2024 campaign stumping for Kamala Harris, flatly refused to back her for another presidential run, and said he would consider supporting a Republican candidate instead.
Cuban made the remarks Tuesday at Politico's Health Care Summit, where senior executive editor Alex Burns pressed him on whether he wanted to see Harris run again. His answer was a single word: "no." When Burns pushed further, Cuban did not soften.
The celebrity entrepreneur and Dallas Mavericks minority owner, once considered a potential Harris running mate before he turned her down, told the Politico audience that he has moved on entirely from the former vice president and her political future.
"Right now, we've got until 2028. I don't care who the candidates are, I'm not trying to pick a candidate, I'm not trying to promote a candidate. I'm trying to change how f***ed up this health care industry is right now. That's all I care about."
That is not the language of a man keeping his options open for Harris. It is the language of a man who watched a campaign lose and decided the whole exercise was not worth repeating.
The sharpest moment came when Burns grilled Cuban on what he remembered about Harris's health care policies from the 2024 race. Cuban's response was blunt: "Don't remember, don't care, those days are gone."
Pressed again on why he would not support Harris, Cuban repeated himself with the patience of a man explaining something obvious.
"I don't care. There's no reason to re-litigate that. It doesn't matter."
What Cuban did remember, and chose to talk about, was the current administration's work on health care. He praised President Trump and his health department for pushing to slash drug prices and fast-track drug trials. For a man who spent 2024 as one of Harris's highest-profile surrogates, the pivot was striking. Cuban's focus has shifted entirely to health care reform, and right now, the administration doing the work he cares about is Trump's.
Cuban also left the door open to backing a Republican in 2028, saying his decision would depend on "what's best for the country." He added a broader declaration about his political loyalties: "I'm not an ideologue about parties. Get rid of both parties, I'm happier."
Cuban's dismissal arrived just weeks after Harris herself teased a possible 2028 presidential run. Earlier this month, during an on-stage interview with Rev. Al Sharpton at his National Action Network conference in New York City, Harris said she was "thinking about" another run for the White House.
The conference also featured other Democrats eyeing the 2028 field. Illinois Gov. JB Pritzker, Maryland Gov. Wes Moore, and former Transportation Secretary Pete Buttigieg all took the stage, a reminder that the jockeying inside the Democratic Party for 2028 is already well underway, with or without Harris.
Harris lost the 2024 election after a campaign that Cuban supported visibly and vocally. That he now cannot, or will not, recall a single health care position she ran on tells you everything about how that campaign landed with even its own allies.
The former vice president has remained active in public appearances since her defeat, including demanding that Trump be blocked from naming future Supreme Court justices. But attention-getting statements are not the same as a viable path back to the nomination.
The Democratic 2028 primary is shaping up as a free-for-all. Pritzker, Moore, and Buttigieg are already making moves. Gavin Newsom has been touring early primary states with a book tour that looks a lot more like a campaign than a literary event.
Harris's name still carries weight in the party, but Cuban's public rejection undercuts one of her core 2024 selling points, the ability to attract business-world credibility and crossover appeal. If the billionaire who once stood beside her on the trail now says "don't remember, don't care," it is hard to imagine the donor class rallying back to her banner.
Meanwhile, other Democratic figures have ducked the Harris 2028 question entirely, a sign that even within the party, enthusiasm for a rematch is thin.
Cuban's willingness to consider a Republican candidate adds another dimension. He did not name names. But the fact that a man who served as one of Harris's most visible surrogates now openly entertains crossing the aisle, while praising Trump's health department, says more about the state of the Democratic bench than any poll could.
Strip away the personalities and the 2028 calendar, and Cuban's comments expose a familiar pattern. Democrats lose an election, their celebrity allies quietly back away, and the candidate floats a comeback before the wreckage is even cleared. Harris told Sharpton she was "thinking about" running again. Cuban told Politico he does not care.
The gap between those two statements is the gap between a party that wants to relitigate and a country that has moved on. Cuban, whatever his faults, at least seems to understand which side of that line the voters are on.
When your most prominent 2024 surrogate cannot name a single policy you ran on and openly praises the man who beat you, the problem is not messaging. It is the product.
