July 15, 2019 — Just before the July 4th holiday break Change Research conducted a series of research studies in three of the first four Democratic presidential caucus and primary states.
The firm tested either 420 or 421 likely Democratic nomination event voters in each place during the period of June 29-July 4: in Iowa (420 respondents), New Hampshire (420), and South Carolina (420).
Iowa is, as we know, the site of the first caucus vote, which is scheduled for Feb. 3, 2020. This will be followed by the New Hampshire primary on Feb. 11 and the South Carolina primary pegged for Saturday, Feb. 29. The Nevada Democratic electorate, with their caucus placed on the calendar for Saturday, Feb. 22, was not polled.
Part of the media coverage surrounding these surveys looks at the aggregate numbers that these three individual places produced. The three states are highly important because they, together, will set the race’s early tone. But, from a statistical perspective, the aggregate total has little bearing as to who would eventually become the Democratic nominee.
These aggregate Change Research numbers, however irrelevant to the actual race trajectory, have captured some attention because they are so close. The sum of the candidates’ support percentages from the combined three states, from a total of 1,261 respondents, find Sens. Bernie Sanders (I-VT) and Elizabeth Warren (D-MA) leading the group with 19 percent apiece, closely followed by former Vice President Joe Biden at 18 percent, Sen. Kamala Harris (D-CA) with 17 percent, and South Bend Mayor Pete Buttigieg posting a combined 15 percent preference. No other even candidate breaks the three percent level.What carries much greater weight, however, is the individual candidates’ status in the individual early trend-setter states. As has been prevalent in Iowa’s electoral history, neighboring regional Midwestern candidates have typically done well in the first caucus. Such is the case again according to this Change Research poll.




June 28, 2019 — Several polls were released just before the presidential debate series began and we see some inconsistency. Former Vice President Joe Biden leads in the most recent national surveys, but by varying margins.



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.
