Not just me. This is common in other countries. People most definitely do not treat their vote as an endorsement. You can believe me or not or say I am bad, but this is a matter of fact.
Being from an “other” country, having lived in another 3 of said “other” countries, an even having been involved in politics in 2 of them, what you wrote is complete total bullshit.
Plenty of people do indeed have an utilitarian view of their vote, but lots of people, maybe even most, treat their vote as an endorsement.
In fact from my own experience in various countries the utilitarian view is more common in countries with less Democratic voting systems with few actually electable choices, similar to the US (so, for example, Britain) whilst the endorsement view is more common in countries with highly Democratic voting systems with lots of choices (such as The Netherlands, which has Proportional Vote).
I’m sorry but whilst you having an utilitarian posture is perfectly valid, your idea that it’s the only valid posture and other people don’t have different postures is complete total mindless self-centred bollocks.
In my experience, how many people vote tactically massivelly depends on the voting system and whether it’s a presidential system or not.
The kind of utilitarian votes that sees one vote for somebody one does not like is not quite an Americanism because it doesn’t happen only in the US (for example, the UK, even though it doesn’t have a Presidential system, has a lot of tactical vote because they use First Past The Post for Parliament so each parliamentary seat is like a mini-presidential election where thare can only be one winner), but it’s not really common in other countries.
As I said, I was involved in Politics in two countries, including canvassing and leafletting, and from talking to people (as well as observing how my family, friends and party colleagues did their “politics”) voting it’s far more often an affair of the hearth than of the head, starting by how people chose which politicians to trust given that they all promise nice things to them.
The cold and rational pondering about who to vote is not actually that widespread and many of those who try are still being swayed by emotional factors (for example, via who they chose to trust and how much) and people tend instead to vote on who they like and trust (or dislike and distrust all of them hence refuse to vote).
Further, even the cold and rational pondering is often not that rational because when it comes to such complex subjects with such a high level of uncertainty and misinformation, most of what one choses to believe as informations and one’s own most favored forecast, is chosen based on less that scientific proof. (There is so much misinformation, disinformation and outright lying that chosing not to chose - i.e. not to vote - might be the most rational option of all).
What I’ve learned from decades of trying to go at things in a rational way is that we can never be fully Objective so it’s a good idea to be aware of and keep track of the Subjective elements in one’s decision making. Sure, it’s valid to try, just don’t decieve yourself that you have a perfectly logical decision making process and that everybody should be reaching the same conclusions as you.
From were I stand, your idea that you have a valid tactical approach and that it THE superior approach without question is just you misleading yourself about the nature of your information gathering and your thinking processes, hence you passing judgment on others for not going through the same obstacle course you do to end up making a decision which was de facto contaminated by subjective elements such as your choice of what information to trust and what forecasts you judged more likely, is like the blind criticing others for not seeing.
You really are not standing on top the moral high ground you think you’re standing on.
