“The only way to remove Trump is to crush Trump. And that’s the question that has to be asked, who can crush Trump? Who’s the street fighter?” Moore said.

But he said that is not enough.

Obama, he said, would be able to crush Trump.

“She would beat him in the debates, he wouldn’t be able to bully her, he wouldn’t be able to nickname her,” he said.

Moore cited Obama’s popular tour for her memoir “Becoming."

“She takes the stage and she’s so powerful and so good you just look at that and think of course she could win,” he said.

Obama, however, is not among the vast field of two dozen Democrats looking to face Trump in 2020.

“Well, has anyone asked her?” Moore said. “If asked to serve, I believe she would serve.”
