No offense, but saying "support my candidate or else the bad man will win" and not understanding that people will see this as a threat is comically bad public relations.
Folks aren't looking for someone to vote against, they're looking for someone to vote for.
Needing to be handled with kid gloves so you don't have to face the weakness of your own rhetoric is privileged.
If you don't get being in a constrained system there's nothing else to discuss. Decide for yourself on who of the two candidates you want, and vote to empower either. Even inaction has a consequence.
I work in cybersecurity, finding ways to break out of "constrained systems" is literally my job.
I also already voted, I'm just not pretending that American "democracy" is anything other than a process for legitimizing an Imperial state.
The voters have no agency, the only people who do are those who constrained the available options to "bad" and "worse". But you're trying to hold those people blameless by insisting that voters are answerable to the party rather than the other way around. The Democrats can't fail, they can only be failed by potential voters who are insufficiently terrified of their "opponents".
The Democrats only need a Republican stick so that they don't have to offer us more carrots, the right move is to stop being a donkey and farm our own carrots.
Let the parties die, the Republican party will collapse to infighting after Trump loses anyway.
