https://www.nbcnews.com/news/amp/ncna1025656 Biden, Harris in virtual tie after dramatic shift in black support, poll shows The latest Quinnipiac survey comes just days after the racial confrontation at last week's Democratic debate. July 2, 2019, 2:00 PM ET / Updated July 2, 2019, 3:54 PM ET By Adam Edelman Sen. Kamala Harris has catapulted into a virtual tie with frontrunner Joe Biden in the race for the Democratic presidential nomination — and she'smade significant inroads with black voters — following her widely praised debate performance last week, a new national poll Tuesday showed. The latest Quinnipiac University poll of Democratic and Democratic leaning voters showed Biden with 22 percent support and Harris with 20 percent — a double-digit jump for her since the university's previous poll last month. Sens. Elizabeth Warren, D-Mass., and Bernie Sanders, I-Vt., were in third and fourth place in the poll, with 14 percent and 13 percent, respectively. South Bend, Indiana, Mayor Pete Buttigieg came in fifth with 4 percent support. No other candidate got more than 3 percent in the poll. Biden's two percentage point lead over Harris was within the poll's margin of error of plus or minus five percentage points. "Round 1 of the Democratic debates puts Senator Kamala Harris and former Vice President Joe Biden on two different trajectories, as support for Harris surges but continues to slip for Biden," Quinnipiac University Polling Analyst Mary Snow said in a statement. "Biden's once-commanding lead has evaporated," she added. The poll, conducted June 28 to July 1, also showed that Harris had caught up with Biden in receiving support from black Democratic voters — a bloc with which Biden has done well. In the latest poll, Biden's support among black Democratic voters shrunk to 31 percent from 48 percent in the June poll. Harris, on the other hand, saw her support among black Democratic voters grow to 27 percent, from 11 percent in the June poll. The June poll numbers on African American voters were provided to NBC by Quinnipiac. The poll suggests a substantial upswing for Harris and a notable decline for the former vice president. In the Quinnipiac's poll of Democratic and Democratic-leaning voters last month, Biden received the support of 30 percent of the respondents, while Sanders had 19 percent, Warren had 15 percent and Buttigieg had 8 percent. Harris had 7 percent support.
