That's one of three results that are unique to a single state. The others are Montana's love of cotton candy-flavored jelly beans and Illinois' love of chocolate-flavored jelly beans, a thing you may not be aware existed until now. (Maybe they're only sold in Illinois?)
Nationally, according to CandyStore.com, buttered popcorn is the most popular flavor, followed by black licorice, cinnamon, and watermelon. Maybe there's something about the data that surfaced divisive flavors, because who doesn't like a handful of tutti frutti?
