A 2020 poll released this week showed former Vice President Joe Biden in a virtual three-way tie with Sens. Bernie Sanders (I-Vt.) and Elizabeth Warren (D-Mass.), but six polls released since then show Biden with a clear lead of as many as 18 percentage points.
Since entering the race in April, Biden has consistently been at the top of polls and the survey showing the tie appears to have been an anomaly. He has an average of 28.5 percent support, compared to 17.8 for Sanders and 16.1 for Warren, in the past six months, according to Real Clear Politics, which compiles polls and lists the averages.
