The chart represents the results of the latest Monmouth University Poll -- done between April 11th and 15th of a national sample of 330 registered Democratic voters, with a margin of error of 5.4 points.
Note that only six candidates garnered more than 2% -- Biden (27%), Sanders (20%), Harris (8%), Buttigieg (8%), Warren (6%), and O'Rourke (4%). I know it's still very early, but the rest of the field needs to start gaining some ground if they want to stay in the race.
