Why did AP call the race?

Republican David McCormick cut into Democratic Sen. Bob Casey's support in Philadelphia and its populous suburbs and built leads in the more GOP-leaning parts of the state, foreclosing the incumbent's pathway to victory when The Associated Press called the race Thursday.

McCormick was leading by more than 30,000 votes when AP called the race at 4:09 p.m., and though there were an estimated 91,000 votes still outstanding at that time, there were not enough in areas supporting Casey for him to make up the difference.

McCormick didn't win in the Democratic-leaning city of Philadelphia. But like Republicans across the map and President-elect Donald Trump, he sliced significantly the support that Democrats got. For instance: Casey was winning the city with about 78% of the vote, but that was down 8 percentage points from six years ago.

McCormick was winning outright in every region of the state — from the Poconos and one-time coal towns to the central areas around Penn State University to Western Pennsylvania. He lost Philadelphia and its suburbs, but cut down the margins. In Bucks County, just north of Philadelphia, Casey was winning by less than 1 point; he carried the populous area by 6 points in 2018.
