I see that the video that was posted here was posted on January 10, 2020, but the latest actual poll that I can find from Ipsos about Democratic Presidential Primary potential voters shows is a January 10, 2020 posting that shows Biden at 23% and Sanders at 20%:

Washington, DC, January 10, 2020 A new public opinion poll shows that Senator Bernie Sanders and Former Vice President Joe Biden are the top contenders for the 2020 presidential nomination. Among Democratic registered voters, Biden (23%) maintains an edge over Sanders (20%) and Senator Elizabeth Warren (15%). Former Mayor Michael Bloomberg (8%) and former Mayor Pete Buttigieg (7%) round out the top five candidates in the race for the Democratic nomination. Among Democrats and independents, Sanders (17%) has a slight lead over Biden (15%), and Warren (10%) maintains her third-place position. Buttigieg (5%) and Bloomberg (6%) are statistically tied among Democrats and independents. All other candidates receive 3% of the vote share or less among Democrats and independents and Democratic registered voters.
Perhaps someone can tell me where the other IPSOS poll that shows Bernie ahead of Biden is and when that one was posted?
