Sen. Kamala Harris of California, who stood at 12 percent in the July survey, saw her support drop in half and now comes in at 6 percent in the new poll. But the Quinnipiac poll found less than half the amount of confidence in Warren defeating Trump, at only 21 percent.
Environmental and progressive advocate and former hedge fund manager Tom Steyer has the backing of 4 percent of likely South Carolina Democratic primary voters, with South Bend, Ind., Mayor Pete Buttigieg at 3 percent, and Sens. Amy Klobuchar and former Texas Rep. Beto O'Rourke raked in 3 percent of respondents.
Warren, the progressive senator from MA, stands at 16 percent in the survey, a jump of 7 points from July.
He holds a massive edge over the field on foreign policy (56% say he would handle it best, well ahead of Sanders at 13% and Warren at 11%), and tops the next closest candidate by almost 20 points on the economy (38% Biden, 19% Sanders, 16% Warren).
Biden toughen has grown with realistic and conservative Democrats, rising to 43 p.c from 29 p.c in September's ballot, and from racial and ethnic minorities, leaping to 42 p.c from 28 p.c in September.
A September Emerson poll had Biden at 25%, Warren at 23%, and Sanders at 22%.
Mr. Biden and Mr. Sanders were running even on who voters think would best handle climate change, at 26%, while Ms. Warren was at 18%. That's up 14 points since the last poll and a whopping 31 points higher than the progressive Warren, his closest competitor among those voters.
Following Biden are Sens.
Cory Booker is scheduled to speak at the National Press Club in Washington at 1 p.m. on Wednesday.
Since I'm a good guy, I'll tell you the answer: Biden is ahead because he is consolidating his support among non-white voters, a key voting bloc among whom he already had a very clear edge over his primary rivals. Potential Democratic voters were asked about the candidates they want to hear more about. The poll has a margin of error plus or minus 4.9 percentage points.
