Screenshot of a thread from @internet hippo that says "There should be public dialogue from Dem leaders about what the medium-long term political strategy against Trumpism is. They don't want impeachment (not enough votes) so what can a Dem congress do that's more effective? Is there a philosophy other than "Vote for us and hope something good happens?" "The voters are stupid" isn't useful analysis or political strategy. They will continue being stupid! You either need a plan to make them not stupid or a plan to win despite that. If the reality is that these are unprecedented times and nobody inked what to do, ok. Let's say that out loud and start thinking. But pretending like we're all living in 1998 and we can wait this out seems suicidal to me
