Here is a summary of the election results in Pennsylvania: (View full map)


Obama won the key swing state, keeping Pennsylvania in the Democratic column. Pennsylvania was a critical part of Obama’s math for winning the 270 electoral votes needed for victory. Pennsylvania last supported a Republican presidential candidate in 1988. Increasingly Democratic since 1992, Pennsylvania emerged as a late battleground. Romney’s campaign and conservative super PACs poured more than $11 million into the state during the final week. Polls gave Obama a lead of about 4 percentage points. For Romney, the state offered an alternative route to the 270 electoral votes late in the campaign as polls showed Obama ahead in some of the states that had been the election’s main battlegrounds, including Ohio and Iowa.


Sen. Robert P. Casey Jr. (D) won re-election to a second term, fighting off a tough challenge from GOP nominee Tom Smith, a retired coal company executive who spent $17 million of his fortune on the airwaves. The race had tightened by mid-October. Casey, an anti-abortion, pro-gun moderate Democrat whose father was a popular Pennsylvania governor, called his opponent “Tea Party Tom Smith” and said he was too conservative for the state. Smith had support from the U.S. Chamber of Commerce and other conservative groups.


In the newly drawn 12thDistrict race in western Pennsylvania, Republican challenger Keith Rothfus, a lawyer, upset incumbent Democratic Rep. Mark S. Critz in one of the most-watched races nationally. The district stretches from Johnstown to north of Pittsburgh to the Ohio border. Critz had defeated Rep. Jason Altmire in the primary.
