There has been a recent explosion of state and national polls in the past several days, and it is difficult to find anything but good news for Bernie Sanders in any of them. I will share cross tabs from one of them, but they all say similar things, including Sanders surging among Black and Hispanic voters - and pulling away from the Democratic pack.
There have been seventeen national polls so far in February from The Morning Consult (3), Emerson, ABC/Washington Post, NBC/Wall Street Journal, Ipsos (2), Survey USA, Marist, Economist/You Gov (2), Hill/ Harris, Monmouth, Quinnipiac and Zogby
Bernie Sanders is on top in 14 of these 17 polls, tied in another, and comes in second in two. He has an eleven-poll winning streak going since the last poll in which he did not come in first.
Over that span of winning national polls, Sanders lead by 10-points versus both Biden and Bloomberg.
