It's confirmed: Amy has qualified for the December debate!

1. Pretty easy also after October

By qualifying before the November debate she is under no pressure in that debate. She and Sanders will both be free to take an easier approach.
November is likely to be Booker's last hurrah and Harris has to arrest the slide.
Biden/Buttigieg/Warren will be going after each other.
Bernie being Bernie can just be himself.

But with really no pressure and likely little incoming Amy can sit back and essentially be supportive to those being attacked. I expect she will support both Biden and Warren given the chance.
