Filmmaker Michael Moore said in a new interview that there is only one candidate up to the challenge to "crush" President Trump in 2020, "and her last name rhymes with Obama."

"In fact, it is Obama - Michelle Obama," Moore said on MSNBC. "Everybody watching this right now knows she is a beloved American and she would go in there and she would beat him."

Moore said it is not enough to have a Democratic candidate who will defeat Trump, noting that his 2016 Democratic opponent, Hillary Clinton, won 3 million more votes nationwide.

"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.

He said four of the Democratic presidential candidates - former Vice President Joe Biden, Sen. Elizabeth Warren (D-Mass.), Sen. Bernie Sanders (I-Vt.) and Sen. Kamala Harris (D-Calif.) - could beat Trump. 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."

Obama is the most admired woman in the world, according to a July YouGov poll, beating out Oprah Winfrey, Angelina Jolie and Queen Elizabeth II.

A former lawyer and University of Chicago dean, she has made no indication that she intends to run for the presidency or any other office.

The Obamas are likely to hold out on endorsing a candidate until one is chosen by the party.

A spokesperson for the Obamas did not immediately respond to a request for comment.
