Black Democrats were nearly twice as likely — 28 percent to 15 percent — to say Biden is their first choice, while Sanders held an 8-percentage-point advantage with the country’s youngest voters (29 percent versus 21 percent). While neither held a significant advantage with men, Biden led Sanders with women by 11 points, 28 percent to 17 percent.

Biden has run for president twice — first in 1988 and more recently in 2008 — and Sanders, the country’s most popular senator among his own constituents, exceeded expectations despite an ultimately unsuccessful challenge against Hillary Clinton for the party’s nod in 2016. They appear to be benefiting from higher name recognition at this early stage of the 2020 presidential conversation.

Fresh off another campaign that exceeded expectations and energized Democrats nationally, Rep. Beto O’Rourke was next in line, securing 8 percent of first-choice status among Democratic voters after losing to Sen. Ted Cruz (R-Texas) last week. Sens. Elizabeth Warren (D-Mass.), Kamala Harris (D-Calif.) and Cory Booker (D-N.J.) followed the Texas Democrat in the list, with 5 percent, 4 percent and 3 percent backing them, respectively.

One percent each picked three other senators who are also potential candidates: Minnesota Sen. Amy Klobuchar, New York Sen. Kirsten Gillibrand and Ohio Sen. Sherrod Brown, who opened the door to a potential presidential run during an interview published Monday with the Cleveland Plain Dealer.

Zero percent of Democrats said their first choice for president was former Attorney General Eric Holder, former Massachusetts Gov. Deval Patrick, Stormy Daniels’ lawyer Michael Avenatti or Rep. John Delaney (D-Md.), who back in July 2017 was first to declare his candidacy for the party’s nomination.

While Biden and Sanders are seen to represent different ideological poles for the left, the survey suggests that’s not top of mind for voters when thinking about 2020. A 35 percent plurality of voters who preferred Sanders said they’d opt for the less liberal former Delaware senator as a second choice, and 33 percent of Biden first-choicers said they’d back the democratic socialist firebrand from Vermont second.
