Sirota: Where are the progressives' red lines?

While Manikin and Dimena are drawing dozens of red lines that will tank Build Back Better if they don't get what they want, and with Biden catering to them to get something passed, where are the progressive red lines? Why aren't they out there making specific demands that if they don't get what they want-meaning what we the people want-then no deal? 

Granted Jayapal has said without passing Build Back Better then no deal. But where is she and her caucus on shaping it with their demands? If you don't make them then surely you won't get them. And so far what Biden has agreed to doesn't seem to include much of the prog agenda. Sure some, but not enough to make enough of a difference to our lives or the environment. Will we except crumbs yet again in this starvation diet killing us and our planet?
