The vast majority of the no voters are only voting that way because they know it will pass with flying colors. They want to be able to smugly tell people they voted no, for whatever nonsense reason they have. If it was down to the wire and they knew their vote would make a difference, they would vote yes. It’s like voting for a 3rd party candidate when you live in Texas or California. They will spend the next 5 years telling everyone they meet that they voted no.
