The Keystone State could be the key to a victory on November 8th.

Pennsylvania, and its 20 electoral votes, are being targeted by both the Clinton and Trump campaigns as the general election contest begins to take shape.

As opposed to 2012, when PA was largely ignored by the campaigns until Romney made a late push that moved the needle but not by enough, the commonwealth is central to 2016’s electoral map.

The Trump camp began articulating a Rust Belt strategy weeks ago and the latest Quinnipiac Poll showed him a point behind.

In an interview with the Tribune-Review’s Salena Zito, the GOP’s presumptive nominee illustrated his interest in the state.

“That is why I always talk about Pennsylvania,” he said of the Quinnipiac survey. “I think Pennsylvania is absolutely one of the states I can turn red.”

Meanwhile, Dan Balz of the Washington Post reports that the Clinton camp is already planning to combat such a strategy from the Republicans.

“The Washington Post’s Abby Phillip described one step that the Clinton campaign is planning to protect states that are must-wins this fall, which is by starting to organize as early and as robustly as possible in Midwestern states with white, working-class constituencies, including Michigan, Wisconsin and Pennsylvania,” he writes.

A Republican has not won Pennsylvania since George H.W. Bush in 1988. The margin of victory, though, was less than ten points in five of the subsequent six contests (the exception being 2008).

Finally, Philadelphia is also of course the host of this year’s Democratic National Convention.

With Pennsylvania as the second-largest swing state in the nation (behind only Florida and its twenty-nine electoral votes) expect a fierce fight for the Keystone State this year.
