Votes that lose by a large margin have no information. They’re commitment free actions taken purely for political gain. Narrow wins are the only ones where you can really learn something.
If everyone else is voting for some necessary evil, it frees me up to vote against it while still wanting it.
I think that effect still exists on small margin votes too. You know pretty much how it’s goona go down on every vote. 99-1 feels a little different to me. That no one else even wanted to claim that lane.
