Billionaire businessman Mark Cuban says gridlock in the government will only get worse if Hillary Clinton wins the White House.

"The customer's always right. The voter's always right," Cuban said on CNN Thursday. "She hasn't done a good enough job of humanizing herself and as a result, post-election, if Hillary wins, if we think gridlock is bad now, if we think approval ratings for Congress are bad now, it's going to be a thousand times worse..."

"You don't buy the Clinton argument that I've been there before, these people know me, they'll work with me?" asked CNN's Chris Cuomo, whose brother, New York Gov. Andrew Cuomo, endorsed Clinton.

"No, of course not," Cuban answered. "Because if you look at what the obstructionism that the Republican Party has offered to Obama, it's going to be a thousand times worse for Hillary Clinton."

Cuban told CNN he could make the argument that Donald Trump would do a better job of crossing the aisle than Clinton, even though he has been a longtime Trump critic. Cuban insisted that Trump will eventually need to go back to the blocking and tackling of campaign politics and said he will also need to trade favors for cash to keep his campaign afloat.

The Dallas Mavericks owner also said he would make a good vice presidential pick for any candidate because, "If there's somebody who could be in the middle and connect the dots, that would be me."
