I’m not sure this is fair. I don’t think this is in lieu of such a conversation, but about some ideas on how to pitch the conversation. If you don’t have any friends in similar circumstances, it’s worth finding out what other people do.
That said, the range of suggestions here is so broad that I’m not sure it’s going to help!
I’m not American (but we do get a lot of US Pol foisted on us), so forgive me if I’m missing something… I thought the US democratic party was basically everyone more left wing than Joe Manchin. There are ‘third parties’, but in general the broad church argument applies… Anyway aren’t USians able to actually pick the candidates that stand for those parties? So wouldn’t you use the generals to vote ‘against’ Republicans, but then use the primaries process to vote for the shape of D you wanted? Here that’s not an option, the party puts up candidates. But you have the ability to pressure the candidates even after they are elected. Might be a long shot, but is inherently less fatalistic than just giving up, or even (as seems disturbingly popular these days) calling for some form of civil war.
