Those are not your typical 80% Obama precincts. The typical such precinct is likely a below-average income inner city area.
BRTD, do you seriously choose where to live based off its voting history? That is, if you found a nice, affordable apartment in a precinct that was only 75% Obama or, God forbid, 60% Obama, you would flatly refuse to live there? Even for you that's absurd.
60% Obama precincts don't exist in Minneapolis, and 75% Obama precincts tend to be quite expensive. Unless it's near the University of Minnesota, in which case I wouldn't live there for other reasons.
I should point out that I already live in a "below-average income inner city area." "Below average income" does not have to mean "poverty stricken ghetto".
You gave an absolute statement. If there was an affordable, well-located apartment in a hypothetical 51% Romney precinct, would you refuse to live there?
