Sounds like a great argument for getting more progressives deeply placed in the party. Too much of the power structure in the DNC is old libs, only way to change that is to get more of us in place.
Would Bernie be more effective if he was formally a member of the Democratic Party, like how AOC is? I'm not sure, but it is telling he ran in the Dem primary instead of as an independent.
If you keep pushing it further open it has a detent that will hold it open far enough that even my big nose won't touch it... It's an amazing design, better than a screw cap in every way. Well, at least the properly designed ones.
