The former Vice President is 24%, Warren is 18% and Sanders is 17% once again the only candidates to receive double-digit support. Three other candidates have 5% or more support or more in the poll: Senator Kamala Harris (8%), South Bend, Indiana, Mayor Pete Butigig (6%), and former Rep. Beta O & Rourke (5%). All other candidates score 2% or less in the poll.
Biden's leader is based on his support among black voters, among whom he leads by a large margin with 42% support and his closest competitor – Sanders – winning only 12% support. Warren (23%) and Biden (21%) are close to white Democratic voters, with Sanders not far behind with 15%. Among Latin Americans who are Democrats or Democrat-independent, Sanders is at 24%, with four other candidates having two digits: Biden at 1
Biden's support among black voters comes mainly from people over 50 (53% in this group support him against 30% among people under 50) and from those who are moderate or conservative (47% in this group support him ). This reflects the model among Democrats more generally, but is more so among black voters. Sanders' strong showing of Latinos comes more from younger Hispanic voters than from older ones.
Warren's support is noticeably increasing among college educated voters – 26% in this group support her against only 11% of those without a college degree. Sanders, whose ideological views are similar to those of Warren, does not have as much difference in education in support of him (19% among those with no degrees, 13% among those with), due largely to his stronger support among whites without college (21% vs. 10% among college graduates)
As they have in past polls, Democrats are more likely to say they want the party to nominate a candidate with a better chance of defeating Trump (55%) over one who shares their position on major issues (39%). But Biden's advantage among those looking for a candidate who can defeat the president has narrowed some since August. In this poll, 35% of those who support someone who can defeat Trump support Biden, 15% Warren and 14% Sanders. Now this group is split almost evenly between Biden (26%) and Warren (21%), with Sanders at 11%.
Democratic voters are more concerned that the party will identify a candidate who is too liberal (49%) than one who is not sufficiently liberal (41%). Biden rates better among those who worry, the party will lean too far left (27% in this group returned it, 15% Sanders, 13% Warren) than those who worry, the nominee will not be enough liberal (27% in this group support Warren, 22% Sanders and 20% Biden.
. Republican polls suggest that Trump will not be challenged by his declared Republican opponents, even as their ranks increase. Overall, 77% say the GOP should nominate Trump for a run president in 2020, about the same as when CNN first asked about it in March 2018, and only 20% would like to see a different candidate nominated.  Trump GOP Leader Mark Sanford says the growing field of Republican candidates is stepping up the anti-Trump message "data-src-mini =" // cdn.cnn.com/cnnnext/dam/assets/190908100447-mark-sanford-file-180721-small-169. jpg "data-src-xsmall =" // cdn.cnn.com/cnnnext/dam/assets/190908100447-mark-sanford-file-180721-medium-plus-169.jpg "data-src-small =" http: //cdn.cnn.com/cnnnext/dam/assets/190908100447-mark-sanford-file-180721-large-169.jpg "data-src-medium =" // cdn.cnn.com/cnnnext/dam/assets / 190908100447-mark-sanford-file -180721-exlarge-169.jpg "data-src-large =" // cdn.cnn.com/cnnnext/dam/assets/190908100447-mark-sanford-file-180721-super-169.jpg "data-src- full16x9 = "// cdn.cnn.com/cnnnext/dam/assets/190908100447-mark-sanford-file-180721-full-169.jpg" data-src-mini1x1 = "// cdn.cnn.com/cnnnext/ dam / assets / 190908100447-mark-sanford-file-180721-small-11.jpg "data-demand-load =" not-loaded "data-eq-pts =" mini: 0, xsmall: 221, small: 308, medium: 461, large: 781 "src =" data: image / gif; base64, R0lGODlhEAAJAJEAAAAAAP /////// wAAACH5BAEAAAIALAAAAAAQAAkAAAIKlI + py + 0Po5yUFQA7 "/>
