That’s up 7 points compared with a late June CNN survey. No other candidate has made meaningful gains over that time.
Biden’s advantage in the poll is boosted by stronger support from self-identified Democrats (31%) than from independents (23%), older voters (34% among those age 45 and older) than younger ones (23% among those under age 45) and from moderate and conservative voters (34%) than liberals (22%).
Among liberals, in fact, the race is a near three-way tie: 23% choose Warren and 22% each back Biden and Sanders. No other candidate even hits 5% among this group.
Biden is also bolstered by those voters who say their top priority is choosing a candidate with a strong chance of beating President Donald Trump, a group that makes up 54% of Democratic and Democratic-leaning registered voters (35% in that group support Biden). That group has shrunk slightly since June, when 61% said defeating Trump outweighed nominating a candidate who “shares your positions on major issues.”
While Democrats do not appear sharply divided on this question by ideology (53% of liberals and 57% of moderate or conservative Democratic voters say beating Trump is more important), race (54% among whites and non-whites prioritize beating Trump) or partisanship (52% of self-identified Democrats prioritize beating Trump as do 59% of Democratic-leaning independents), there are notable divisions by age and by education among whites, which highlights the challenge facing candidates when they attempt to appeal to those on both sides of this line.
Among those under age 45, 56% say it’s more important to nominate a candidate who shares your positions on issues, while 66% of those age 45 and older say it’s more important to nominate someone who can defeat Trump. Among whites without college degrees, 49% say it’s more important to nominate someone who shares their view on issues while 45% say beating Trump is more important, but among whites with a college degree, 65% say it’s more important to beat Trump.
Washington Gov. Jay Inslee’s campaign said Monday that he had hit the 130,000-donor threshold. Inslee has not hit 2% in any qualifying polls.
New York Sen. Kirsten Gillibrand has hit 2% in one qualifying poll and is the only other active candidate to have hit that mark in any qualifying poll, but she has not met the fundraising criteria.
Asked which candidates they’d most like to hear more about, Democratic and Democratic-leaning registered voters are largely focused on the people who will appear on September’s debate stage.
The 10 candidates named by 5% or more of respondents have all now qualified for inclusion in the debates. Warren now tops this list, named by 20%, despite a slight decline in interest in hearing more about her compared with June. She is followed by Harris at 18%, Sanders at 16%, Biden at 15%, Buttigieg at 13%, Booker and O’Rourke at 10% each, Yang at 6% and Castro and Klobuchar each at 5%.
The CNN Poll was conducted by SSRS August 15 through 18 among a random national sample of 1,001 adults reached on landlines or cellphones by a live interviewer. Results for the full sample have a margin of sampling error of plus or minus 3.7 percentage points, for the subsample of 402 Democrats and Democratic-leaning independents who are registered to vote, it is 6.1 points.
