The dems are one of the only groups in the US who (legally) had the power to:

• reduce voter suppression
• fix the electoral system in general (e.g. remove the broken FPTP system)
• stop sabotaging popular candidates
• not choose a senile dementia-sufferer to remain the country’s leader for years
• support the worker class instead of the owning class and get their votes (too many things to list)
• support US citizens instead of imperial interests in countries half the population can’t plot on a map

For most of these things, they should have been doing this long, long ago, before even Obama’s terms. The Democrat Party clearly had the power of the state for more than enough time to make them look like an alternative rather than a complicit ally of the Republican Party. Why should they not be seen as at fault?
