The dictum has been “when faced with a choice of evils, choose the lesser.” In politics, that has not worked.
It would be ironic if the utilitarian strategy of voting for the lesser evil failed on utilitarian grounds, but that does seem to be what’s happened. Maybe it shouldn’t be surprising. As with all shortcuts, it may be the nature of utilitarianism that it seems to work at first, then fails later; at which point, Hey look! another shortcut is offered.
What seems the pragmatic way to get things done, is not. What seems difficult and foolish is the only way forward. Anyway, I’m done with voting for the lesser evil. It seems illogical to say “when faced with a choice of evils, don’t do evil,” but maybe that’s the way to go.
