Still looking for clues on how Tom Corbett picked up his stunning upset of Dan Onorato in Democratic Allegheny County? The Pittsburgh Neighborhood and Community Information System is up with their election maps on their Pittsburgh Urban Blog, which should give us some clues.

Corbett cleaned up all over the county (see above), picking up most districts outside the city of Pittsburgh. They also found (below) that turnout grew in suburban districts, while it was down in much of the city.

Our thanks to Chris Briem for the heads-up.
