Harris Faulkner said Wednesday on Outnumbered that in order to defeat President Trump in the 2020 election, Democrats will need to learn "how to break history."

Faulkner pointed out that the country has seen just one incumbent commander-in-chief lose a re-election bid since 1984, which was George H.W. Bush.

"It is really hard to beat an incumbent president," she said. "I think the Democrats have to figure out not just how to beat Trump but how to break history, and I'm really curious to know how they're gonna do that."

Fox News analyst Marie Harf said that many Democratic voters say their primary goal is to beat Trump in the polls.

She said that those voters would like to see a more moderate Democrat win the party's nomination.

"They want Joe Biden to run, they want Beto O'Rourke to run, they want Mitch Landrieu to run. These are people they think are the real future of the party based on how we did in 2018," Harf said.

Faulkner also noted that 2020 candidate and Vermont Sen. Bernie Sanders (I) raised about $6 million in one day following his announcement to enter the race.

"We haven't seen that since Barack Obama. And that's problematic for Democrats," she said.

Kennedy said that many top 2020 candidates are talking out of both sides of their mouths, and that they have to be "incredibly careful."

"You can't have it both ways," she said, adding that people can't have Medicare for all, free college tuition and a universal basic income with no way to pay for it.
