If you think President Donald Trump is more colorful and outspoken than previous presidents, you haven't seen anything yet, former White House strategist Steve Bannon told Politico.

Bannon weighed in on the 2020 election in an interview published Thursday, saying Trump will be in "payback mode" if he wins reelection and that he won't be beaten with policy-centered arguments.

"You’re going to get pure Trump off the chain. Four years of Donald Trump in payback mode."

He also praised Massachusetts Sen. Elizabeth Warren, who has her eyes set on the White House.

"Elizabeth Warren has an incredibly detailed and probably the most well thought-through set of policy prescriptions, and they keep coming every day," Bannon told Politico.

"Every other day I see another person jumping into the race," he said. But he said he doesn't "see anybody in that field as of now who can take on Trump one-on-one."

Bannon, who served as the CEO of Trump's victorious campaign, predicted in February during an interview on CBS' "Face the Nation" that his former boss would win again "bigger than he won in 2016."

He also predicted then that "2019 is going to be the most vitriolic year in American politics since before the Civil War."

"And I include Vietnam in that. I think we're in, I think we're in for a very nasty 2019," he said.

Bannon lost his White House role in August 2017 after John Kelly became chief of staff.
