Washington (CNN) Entrepreneur Andrew Yang said Saturday that the still-wide Democratic presidential field needs to unite, and joked that someone ought to "pull an Andrew Yang" and drop out of the race.

"The rest of the field needs to consolidate, ideally," Yang said on CNN. "And each candidate wants to be the last person standing to absorb the non-Bernie energy," meaning front-runner Sen. Bernie Sanders of Vermont.

"Someone needs to pull an Andrew Yang," Yang said with a laugh, referencing when he ended his own presidential campaign just last week. At the time, he told supporters he had done the math and did not see a path to secure the nomination. Yang has since joined CNN as a political commentator.

His comments come after CNN projected Sanders would win the Nevada caucuses . The senator's projected win in the state follows a win in New Hampshire and a strong showing in Iowa , where results are still being examined from the state's caucuses and former South Bend, Indiana, Mayor Pete Buttigieg holds a narrow lead.

"The problem for Bernie is that, you know, he's unlikely to get an outright majority of delegates heading into the convention, which is going to set the stage for the superdelegates to emerge, and then you're looking at a contested convention," Yang said.
