Dallas Mavericks owner Mark Cuban doesn’t think Donald Trump’s Scrooge McDuck money vault is as flush with cash as he says it is.

“He has been bragging that he is worth north of $10 billion,” Cuban wrote on his “Cyber Dust” app (via USA Today). “Ok. While it’s a big number, it’s not an important number. In fact it’s a play number.”

He continued: “Let’s say you own a painting that gets appraised at $10 billion. That gives you a net worth of 10 billion. But that does not mean you have a lot of cash. How much cash does Donald have? We don’t know for sure. But we do know whatever cash he has, post his several corporate bankruptcies, he hates to spend it. And the one thing about the race for the Presidency is that it takes a lot of CASH.”

Cuban concludes Trump “bragged himself into a position” that he won’t be able to finance.

“[H]e can’t afford the cash it takes to run for President,” Cuban wrote.

Cuban, who fancies himself a devotee of libertarian icon Ayn Rand, has long been critical of Trump and vice versa. In 2012, the two got into a heated Twitter argument about money. Cuban offered to donate an additional $1 million to Hurricane Sandy relief if Trump would shave his head. Trump did not take kindly to the dare.

Only 1 mill. dollars @mcuban? Offer me real money and I’d consider it. Your team and networks lose so much money I doubt you have much left! — Donald J. Trump (@realDonaldTrump) November 5, 2012

Dummy @mcuban is at it again trying to use me to get publicity for himself! — Donald J. Trump (@realDonaldTrump) November 5, 2012

Trump has not responded to Cuban’s latest jabs, but then again he’s been too busy possibly fishing for a donation from golfer Zach Johnson, who won the British Open on Monday.
