In a national poll released today by Emerson College Poll, Donald Trump loses to all Democratic rivals that were surveyed.
Emerson found that Sanders and Biden both defeating Trump by 55% to 45%. Warren leads by 6% (53%-47%). Harris and Buttigieg lead Trump by 4% (52%-48%).
The national Emerson College poll was conducted June 21-24, 2019 under the Supervision of Professor Spencer Kimball. The sample consisted of registered voters, n=1,096, with a Credibility Interval (CI) similar to a poll’s margin of error (MOE) of +/- 2.9 percentage points. The data was weighted by age, gender, region, income, and education based on 2016 turnout modeling…
Using the 2016 turnout model would seem to be very conservative since all indications are that 2020 elections should have extremely high turnout, benefiting Democrats.
A similar poll showing Trump beaten by all the leading Democrats was released June 11 by the Quinnipiac University poll.
Presidential polls by state, mostly 2019.
Mississippi Poll Shows Biden Dominant Over Other Democrats
Joe Biden has support of 50% of voters. Warren and Sanders each get 7%, and 21% are undecided.
Biden has the support of 58% of African American voters. Likely he benefits from his connection to Barack Obama, and the perception he is the strongest candidate against Trump.
