Going for a bit more population, there are some 90+ wards in Madison WI that are whiter than this Williamsburg precinct, all roughly on the east (i.e. non-university) side of the central isthmus.
Ward 32 - 84% white (87% by VAP), Obama 90% (Obama-McCain-other raw vote: 1,596-129-43)
Ward 33 - 91% white (93% by VAP), Obama 93% (2,355-133-51)
Ward 34 - 88% white (90% by VAP), Obama 94% (2,595-117-56)
Ward 35 - 90% white (90% by VAP), Obama 93% (1,645-75-47)
Ward 38 - 89% white (90% by VAP), Obama 90% (1,202-78-36)
Geez, and these wards are from the non-university side of town? Obama presumably did even better in the UW neighborhoods, right? Though maybe those may not be as white? I dunno.
Remember that universities usually take students from a large area, so tend to actually be locally conservative in highly Liberal areas. UC Berkley is the most Conservative part of the City of Berkley, since not all people who attend Berkley share the city's 90-95% Democratic voting tendencies.
I assume the UW areas have some Conservative youngsters from the Milwaukee burbs (and elsewhere)--at least more than 1 in 10 I'd assume.
Or they might be too Asian to qualify, but I wouldn't really know.
