That’s your prerogative, just recognize that if both options support genocide and block strikes, so you chose to vote for a non viable candidate, or to not vote, you’re effectively disenfranchising yourself.

Your last point is very valid though. The DNC is very good at shooting themselves in the foot because they should know very well that people do get demotivated and just stop voting, yet continue to distance themselves from their voter base, resting on their laurels as “the only sane choice out of the two”.

Supporting local candidates, where your vote also is more heavily weighted, is one of the ways to shift policy - the US govt isnt just the president, it’s representatives and senators and state governments.
