Does not function as a party (single defectors routinely kill major legislation without consequence)
Is incapable of countering the rising tide of fascism, or unwilling to do so
Has no plan to address the Supreme Court, which will continue to kill anything legitimately good if left unchecked
Is too beholden to capital to push even the most tepid climate change legislation (the Green New Deal)
Constantly attacks its left flank, preferring to chase the votes of suburban reactionaries
Isn't even reliably pro-labor
Tailed popular movements on all sorts of civil rights issues
Still can't be bothered to even de-schedule marijuana, the most slam-dunk popular policy one could imagine + a huge driver of mass incarceration
Is on basically the same page as Republicans with respect to foreign policy
Generally offers nothing besides "at least we're not as bad as Republicans, most of the time"

Where is that party going? It's never going to meaningfully address climate change, it offers only crumbs to the working class, and any social change has to be led from the outside.
