There was an episode of Community where six members of the study group voted on whether or not to kick a seventh member out of the group.
They didn't say that a 4-to-2 majority would be enough to kick him out, they said that it must be unanimous. They'll only throw him out if it's 6-to-0 in favor of throwing him out. If even one group member said that he deserved to stay, then the rest would have to go back to tolerating him, because that one person's opinion matters, and the group didn't want to take anything away from anyone.
That's not a failure of democracy, it's just something that should have been explained before or after the poll.
In that instance that one person would be losing out on something. In this instance the original kickstarters don't lose anything.
