I've been doing this shit since Bush. Things have gotten worse due to bootlicker apologia and you're in for a longer haul than 2 years.
Do your caucuses and primaries, sure. Local politics are important. But also point out the massive and consistent failings of party leadership and call for their removal. The DNC has to go. We have to have radical policies instead of tepid incrementalism.
When you work with christian fanatics (i.e., anywhere in the US) in an office that "respects religious diversity," bullshit cultural norms are enforced.
I work out of an office within sight of a megachurch- and spend as much time in the field as possible.
