Biden and Sanders formed a top tier with no clear leader indicated: the former vice president averages 27% support among registered Democrats and Democratic-leaning independents or likely Democratic voters, while the Vermont senator averages 24%.
Following the top two are Massachusetts Sen. Elizabeth Warren with 14%, former New York City Mayor Michael Bloomberg with 8%, former South Bend, Indiana, Mayor Pete Buttigieg with 7%, Minnesota Sen. Amy Klobuchar with 5%, businessman Andrew Yang with 4%, and businessman Tom Steyer with 2%.
Following a new NBC/WSJ poll out Friday morning, the CNN Poll of Polls is an average of the six most recent nonpartisan, live operator, national surveys on the race for the Democratic presidential nomination conducted among potential Democratic voters.
While Biden had been a consistent leader for much of the race, Sanders has challenged Biden's position in several recent polls, placing him in a top tier with Biden.
The new NBC/WSJ poll shows a tight race with Sanders at 27%, Biden at 26%, followed by Warren at 15%, Bloomberg at 9%, Buttigieg at 7%, Klobuchar at 5% and Yang at 4%.
Among those who have a first choice for president, 45% say they'll definitely support that candidate, 27% say probably, and 27% are "just leaning towards voting for candidate."
Sanders supporters are much more likely to say they'll definitely support him (60%) over Biden supporters (48%). A third of Democratic primary voters say they're "enthusiastic" about Sanders versus 26% who say the same of Biden and Warren each, 16% for Buttigieg, 14% for Klobuchar, 12% for Bloomberg and 5% for Steyer.
Almost three-in-five potential Democratic voters say they've seen an ad for Bloomberg (59%), significantly higher than any other candidate. He's followed by a third who've seen an ad for Steyer (33%), 28% for Sanders, 25% for Biden, and 24% for Warren.
