David Broder paints a picture of this year’s unique gubernatorial contest in the Keystone State in the Washington Post.

If they choose Democrat Dan Onorato, the 49-year-old elected executive of Allegheny County (Pittsburgh), they will end a 64-year period in which the governorship has alternated between the parties every eight years.
On the other hand, if Republican Attorney General Tom Corbett, the early favorite, wins, he will have succeeded where every other attorney general who tried for the top job failed.
