As I said a couple of pages ago about belief and legislation of/based on it: the problem is not the legislation, nor is it the object of said belief. The problem lies with belief itself, we picture ourselves as rational and informed members of the in-group, we "know" the "truth of things" because our group agrees with us.
The idea that the vast majority of what we "know" doesn't even begin to possess qualities to count as knowledge, or that the rightness of an in-group is perceived just as wholeheartedly as wrongness to an out-group, well, that sort of thing involves doubt.
Doubt is the longest four-letter word ever, which probably explains why it is often treated as more insulting than so many of the others.
"Fuck you for your position."
'Whatever, you're an asshole.'
"I doubt the beliefs your position is based on."
'How dare you question something I hold to be true?'
This election highlights that problem so very well: it ended up being decided as a choice between two out-groups, and which one was more virulently opposed by the complementary in-group.
This was not an election about "my position is right, my in-group is correct" at all, it was a rejection of the positions/wrongness of the out-group.
You get people like me who were so baffled by the outcome because we were trying to explain why various things were actually right, or at least likely, but if it is difficult for someone like me--who prefers to avoid being associated as a supporter of the Democrats or Republicans--to explain it based on reason and information, and is used to lacking the passion and fervor which comes with believing in a position... how could people who usually make use of their affection for a candidate handle a situation where there was no love and excitement about who they got?
It was easier for one side to accept a wild divergence from their usual positions, hold their nose, and vote for someone they openly despised, than it was for the other side to get people to care about their candidate even though she wasn't actively hated, and rode the usual positions like a professional bull rider.
There does seem to be an option for not wasting votes though, was mentioned a couple pages back: have people rate the various candidates, go with the one who ends up actually rated the highest.
"How well do you think this candidate would perform if elected? [Terribly -- Average -- Excellently]"
Nobody really expected that Trump would even be an average president, much less an excellent one, not even the people who voted for him. Yet many of the people who voted for Trump would probably confess that Clinton wouldn't be terrible as president, just that she would be "more of the same" so they were forced into choosing "Hillary" or "literally-anyone-but-Hillary" whether they wanted this to be the case or not.
If you went to Amazon and forced every single reviewer who gave a 2-3-4 star review to choose between 1 star or 5 stars the outcome would be different because there are lots of people who say things along the lines of "this product was great, but..." or "I was overall disappointed with this, but..." and their 2~3~4 star votes make sense in this context.
"I really liked this, but I wasn't able to make use of it because it didn't have a feature which I discovered was important, so... I guess 5 stars?"
"I actually meant to purchase something else, but after trying this I am more certain that it is not the worst option, simply not my preference... but I gotta give it 1 star."
