“Keystone Renewal is all in to elect David McCormick to the U.S. Senate,” Mr. Dorr said. So far, Mr. Casey’s campaign and the Democratic Senatorial Campaign Committee, the main campaign arm of Senate Democrats, have spent the most on ads in the race. The committee has spent about $9 million on broadcast, cable and digital ads, while Mr. Casey’s campaign has spent $8.5 million. “Pennsylvanians already know that McCormick can’t be trusted.”The Pennsylvania race is one of only a handful this year expected to determine control of the closely divided Senate. Mr. McCormick, a former hedge fund executive, is making his second bid for a Pennsylvania Senate seat in as many years.
