I probably have somewhat lower standards for Democrats than Republicans, actually -- because both parties will rule America about half the time, it makes sense for me to vote for better-than-replacement Democrats, who will then hopefully have more of a voice in their parties, even if I would find a Republican with the same views very distasteful. In the past I've used gun rights as a good litmus test, with people like Manchin/Donnelly/Heitkamp getting my hypothetical vote so that the Democratic Senate caucus is more pro-gun-ownership, though as the conservative victory on this issue gets more entrenched and it becomes less relevant I'll probably need to find something else.
I used to have this approach, and it's why I voted for Steve Glazer when he ran for state Senate. Then covid rolled around and he was one of the loudest and worst advocates for eternal lockdowns and all sorts of other bad stuff. Not making that mistake again.
No one aside from Arthur Chu who is no longer relevant in the slightest and perhaps a few other Twitter clowns was calling for "eternal" lockdowns.
