Just how much of a threat are Sanders to Warren and Vice Versa?

[RTFirefly]

From the “Biden’s In” thread:

@RTFirefly

It’s not just Iowa; Biden’s national numbers are also dropping:

538’s latest national polls:

Ipsos, 5/29-6/5: Biden 31%
YouGov, 6/2-4: Biden 27%
CNN, 5/28-31: Biden 32%

Looking less invincible by the day.

@Chronos

OK, so there’s one singular poll where Warren is only a little behind Sanders, instead of a lot behind him.

In those same polls I listed above, Sanders’ advantage over Warren is 5, 3, and 11%, in that order.
