Democrats simply have no levers to pull to make wholesale changes. I remember Hillary attempting to engage with healthcare reform during her time as First Lady and being pilloried for it. Obama's administration couldn't muster nearly enough votes to enact single-payer healthcare and had to opt for a market based solution that just eked through congress, only to be lambasted by the modern left for it.

Many around these parts act as if Democrats can just enact reforms by fiat and do not answer to a largely centrist, if not conservative, constituency. A cursory examination shows this has never been the case; the center/left has always had to govern via consensus.

Now "leftists" are eating their own to a degree that leaves me often suspecting that many are little more than poorly disguised MAGA adherents bleating accelerationist nonsense. This thread and any other like it is replete with these moans of surrender, and who can be surprised? Organizing takes much more effort than vomiting into a keyboard and these folks are by and large too lazy to suss out an understanding of recent history, instead choosing to repeat the same canards (see: the conspiracy theory of independent Bernie being cheated in lieu of not being able to come close to winning the Democratic primary.)
