I think I've found what might be the worst precinct for the marriage amendment in the state, and it's not in the Twin Cities:
NORTHFIELD W-1 P-1
Yes 55
No 1081
Estimated Blanks 18
Estimated Total Number of Voters 1154
Estimated Percent of YES* 4.77%
Carleton College, where Paul Wellstone used to teach. Not that surprising. 87.6 Obama/8.3 Romney by the way.
The likely second worst though is in St. Paul:
ST. PAUL W-3 P-07
Yes 101
No 1347
Estimated Blanks 18
Estimated Total Number of Voters 1466
Estimated Percent of YES* 6.89%
Macalester College.
Minneapolis' worst precinct for it (and likely third worst in the state) is not a university:
MINNEAPOLIS W-10 P-01
Yes 149
No 1818
Estimated Blanks 16
Estimated Total Number of Voters 1983
Estimated Percent of YES* 7.51%
An area in the Lowry Hill East neighborhood near the heart of hipsterdom but not quite in it, meaning it can have big houses and reasonably affluent (and of course well educated) people who still are close to enough their organic food co-ops, coffee shops and indie movie theaters. And not many minorities.
Augsburg College, a Christian university that started exclusively as a Lutheran seminary was actually the strongest college precinct in Minneapolis for the "No" vote with 87.78% No/blank, the University of Minnesota and nearby student neighborhoods averaged around 83-84% No.
The worst legislative district for the marriage amendment was 61A, which of course contains Minneapolis W-10 P-01, and is a bunch of affluent neighborhoods around the lakes in the southwest that sits near the hipster paradise in Uptown, it was almost 88% No/blank and still voted "only" about 78% for Obama. My own 62A had a fairly embarrassing 28.48% "Yes" vote since it ran strong in some minority neighborhoods here, for example it broke 57% in Minneapolis W-06 P-05, an area that is basically nothing but almost exclusively Somali-populated public housing projects where Obama still broke 90%. At least my precinct was over 88% No/blank and better than all of 61A.
