She got 75% of Kaplan's votes there, impressive
About 60%. Peralta got around 20%, and 20% were exhausted.
It could be close enough that the limit of 3 choices may have been decisive.
Well, the final round had 6873 voters who had voted for 3 people, and had them all exhausted. However, many of those might have been multiple times for the same candidate (for example 488 of them voted for Kaplan 3 times), and there's no reason to believe that they'd necessarily heavily favor Perata over Quan on a hypothetical 4th ranking.
OK, 5132 of those voted for unique people, and so some of those might have wanted a 4th choice. Another 1741 did things like vote for Kaplan 3 times.
2.5 times the margin. Highly unlikely that it would have changed much, of course (given that Kaplan's voters preferred Quan over Perata, it's unlikely that those who cast two votes for no-chance candidates plus one for Kaplan would have favored Perata over Quan), but still too semi-possible for comfort.
