Bernie Sanders telegraphed a possible drop-out after next debate:

[Demsrule86]

42. I think if his words and ideas were so so

important, Sanders would be winning...go ahead...and threaten all you want...you will drive the party to the right if you continue. And the left will have less influence than before. It is your choice if you want to be in the tent...and if you don't, we will win without you ;the first example of this was in 18 when moderates won the house. We can't pass M4A through the house at this point. By not voting for Democrats in 16, the left/green (Stein voters yuck gag) caused the party to move right not left and the ironic thing is this makes their policy less likely to pass a Democratic Congress. If we win back the Senate, it will be in red/purple states...not left leaning states so again...we will get some good policy through but probably not the Green New Deal or MFA.

As for the Debate, I have no worries about it. The primary is over and a debate won't change that. Biden will be fine. I might watch it because I like to hear Biden...but honestly, I turn the sound off when Sanders speaks...so done with him and the primary. He has less than half the support he had in 16...really sad in a way.
