The following can all be true:

• The Democrats are a right wing neoliberal party.
• The Democrats are the most left-wing option that is realistically available to American voters.
• The Democrats can be pushed further left if American progressives work to do so.
• The Democrats - at the party level - will resist such a change, but that resistance can still be overcome.
• In the long term, massive structural overhauls and the downfall of capitalism are the only things that will save America and the world
• In the near term, voting consistly and enthusiastically for the least bad option can still protect vulnerable groups from harm and create changes that lay the groundwork for those structural overhauls.
