Sen. Elizabeth Warren (D-MA)
Biden, on the other hand, began with an unweighted 20.4 percent preference from a universe of over 5,000 individuals from which selected respondents were polled in April. This was the best score among the candidates at the time, but the former vice president and veteran senator began to seesaw through the succeeding months after rising to a high of 29.6 percent in May. Gradually he began dropping to his September level of 18.0 percent, now well behind Sen. Warren and less than one point ahead of Sen. Bernie Sanders (I-VT).
The September weighted numbers from the 599 most likely Democratic primary voters find Sen. Warren leading with 29 percent, Sen. Sanders moving into second with 21 percent, Biden with 18 percent, and home-state Sen. Kamala Harris dropping to just 11 percent from her high of 20.6 percent in July.
The California vote is critically important to winning the nomination because the state possesses 416 first-ballot delegates at the Democratic National Convention. Texas has the second-largest delegation with 228 first-ballot delegates, thus providing a measure of California’s prominence within the Democratic nomination process. Under the weighted percentages, Sens. Warren, Sanders, and Biden would be the only candidates to qualify for delegate apportionment because they would exceed the minimum 15 percent threshold.
The underlying questions asked of September’s weighted respondents reveal an even more stark difference between Warren and Biden. It is here where we see a fundamental shifting of strength between the two, with her on the ascent and him falling back.
