The Keystone State's stunning county-by-county results

By just about any measure one of the biggest surprises of election night was Pennsylvania going red.

Almost every expectation was that the Keystone State, blue in presidential years since voting for Bill Clinton in 1992 -- and a state that picked Hillary Clinton over Barack Obama in the 2008 Democratic primary -- would once again go Democratic.

As the president-elect might say: WRONG.

And the extent of the switch from blue to red is impressive, as vividly displayed in a map and graph offered up Thursday by the Pittsburgh Tribune-Review.

You can see it right here. Just scroll down in the news story to where it says "jump to map."

In a nutshell, it points out that Trump did better than Mitt Romney in 58 of the state's 67 counties, and that Clinton did worse than Barack Obama in 65 of the 67.

Chester and Montgomery counties are the only two in which Clinton out-performed Obama (in fact, Chester last time narrowly went for Romney), and Trump won three counties -- Erie, Luzerne, Northampton -- that Obama carried in 2012.

But margins within Trump-carried counties explains why Philly and its suburbs, despite their much-touted electoral clout, were not enough to hand Clinton the state.

For example, in more than one-third of our counties, 23 of 67, Trump won 70 percent or more of the vote. And in three counties, he won 80 percent or more.

The three are Fulton County (84 percent) along the Maryland border in Central Pa.; its next-door neighbor Bedford County (83 percent); and Potter County, along the New York border in Northwest Pennsylvania.

By contrast, Romney in 2012 won 70 percent or more of the vote in just seven Pa. counties, and in no county here did he win 80 percent.

So Trump and his supporters were right when they talked about the depth -- mostly unseen, unheard, and missed by the media -- of his support in Pennsylvania.

There's a long list of ways the Trump campaign shattered conventional political wisdom, virtually from its beginning. But turning Pennsylvania red has got to be pretty high on the list.
