The butteryfly ballot was an approved but confusing ballot that almost certainly cost Gore the election. But what is the remedy? There's no other choice but to have a better ballot next time. "The voters were confused by a legal and approved ballot" can't be the basis to overturn an election or it'll never end.

Another good example of this is how Alaska adopted ranked choice voting. In 2022, the 2 Republican candidates got more combined votes than the Democrat who ultimately won [1]. Do you think That was the intent of the voters? Almost certainly not but the electorate just didn't understand RCV and enough people only ranked 1.

In 2024 there was only a single Republican on the ballot so it wasn't an issue [2].
