And most of those boil down to “voting for X decreases the things I care about increases the things I don’t care about; therefore those who care about those things are voting insane.”
It’s inherently an argument that democracy does not work.
Voting "insane" is very different from voting "selfish".
Clearly, voters are not casting votes based on objective measurements of the things that some candidates believe are important to them (e.g. household income, life expectancy, health care quality etc).
But that means either that they are voting based on other issues that they consider important, or they are not voting based on likely outcomes of a candidate's policy preferences at all.
It's not trivial to differentiate these two (and of course, there may even be a mixture of all 2, or even all 3, reasons to vote).
