Merely disagreeing with the way another person plans to vote isn’t tantamount to questioning that other person’s morality. Insisting that “It’s morally imperative to vote my way” or “Those voting differently from me are _____” where _____ is some sort of moral flaw (preening, cowardice, squeamishness, etc) isn’t just disagreeing with how others plan to vote, though.

I look at the question, “Do the odds in my state of my vote flipping the election to the victor give me a moral obligation to choose between the two leads?” as a prudential question that depends on a judgment call about those odds. Knowing the lottery-like nature of those odds, typically even in swing states, I can understand anyone answering, “No.” I can also understand those in swing states answering yes. Or anyone answering yes for himself, if entering the lottery for the victor, even with the smallest odds imaginable, is important to him. Where to set bounds like “so close to zero it may as well be” is always a judgment call in decision making, not something that can be established by mathematical proof.
