Washington, Sep 18 (TIWN) Former US Vice President Joe Biden is leading the Democratic primary of the 2020 presidential election, trailed by Senator Elizabeth Warren from Massachusetts in the second place, according to a national NBC News/Wall Street Journal poll.

 The poll finds Biden garners 31 percent support from Democratic primary voters, up from 26 percent in July, followed by Warren with 25 percent, up 6 percentage points from two months ago.  Bernie Sanders, senator from Vermont, came in third with 14 percent of support, and Pete Buttigieg, mayor of South Bend, Indiana, ranked fourth with support rate unchanged at 7 percent, according to the poll.  Kamala Harris, senator from California, lost 8 percent to garner 5 percent this time round. 

In light of ideology, race and age, the results showed that Biden led among moderates or conservatives, African Americans, as well as older Democratic voters, whereas Warren got overwhelming support from self-described liberals and white Democrats.  The poll was conducted on Sept. 13-16 with a margin of error of plus and minus 4.36 percent.
