The Associated Press called the race for Republican David McCormick when Casey was trailing him by about 30,000 votes.

Democrats will keep their majority control of the Pennsylvania state House of Representatives next year after holding onto a Johnstown area seat.

Democrats maintain control of Pennsylvania House of Representatives with a one-seat margin.
