Change Research has polled the Democratic horse race in California six times since April. This is the first poll without Senator Harris in the race. While Sanders has continued to climb, Warren experienced a slight drop since our last poll in October. Biden has stayed relatively steady since July, and Buttigieg has slightly increased since October. Although Bloomberg polled at 3% in the December poll, he is not on this trend graph because this is the first poll Change Research has polled with him in the race.
