Has anyone else noticed that the latter tend to be far more Democratic? I observed this in Mankato and found something rather interesting on this map:http://www.dfl4cd.org/finder/zips/precincts/maps/Hennepin/Mpls_Election_Precinct.pdf
2-11 was Bush's second best precinct in Minneapolis (the first btw is 7-10, the only one he won which contains an Assemblies of God university). 2-4 was his fourth best. (His being 12-7, and why should be obvious from the map.)
Hardly the case with the off-campus precincts though. Apparently College Republicans are more likely to drop out, or there's some effect from living on your own and working instead of just having your parents pay for you and your housing.
