Aug. 14, 2019 — The HarrisX polling firm just completed conducting three rolling national Democratic presidential primary polls, and while they confirm other data finding former Vice President Joe Biden leading the race, he does so only in the low 30s. This is a number range far below what he needs to win a first-ballot nomination. The data does, however, reveal a new contender consistently placing second.

Sen. Bernie Sanders of Vermont
The HarrisX findings when compared with other recent polling yield a first-place finish for Biden. The three studies post him to a pair of 30 percent finishes and one 31 percent showing.
But, perhaps the more interesting placement comes in examining who finished second. In contrast with the conclusions of other national polls that show Sen. Elizabeth Warren (D-MA) placing definitively in second place, the HarrisX series finds Sen. Bernie Sanders (I-VT) returning to that position.
The three polls project a consistent Biden-Sanders-Warren finish, with the leader scoring close to a 2:1 margin over his closest rival.
The research trifecta produced the following results:
| Aug. 9-12; 1,346 registered or self-identified US Democratic voters | |
|---|---|
| Biden | 30% |
| Sanders | 16% |
| Warren | 10% |
| Harris | 6% |
| Buttigieg | 5% |
| O’Rourke | 4% |

June 25, 2019 — There have been several important state polls recently released that provide us data about where the Democratic presidential candidates stand in relation to popular preference. But that is only half the story.
June 17, 2019 — A new large-sample Golden State poll released from the University of California at Berkeley and the Los Angeles Times (June 4-10; 2,131 likely California Democratic primary voters from a pool of 4,435 registered voters) yields some surprising results. The three most unexpected findings first show a tight race among the four top contenders, Sen. Elizabeth Warren (D-MA) surging into second place, and home-state Sen. Kamala Harris only finishing fourth but not substantially behind.
