Democrats join 3rd televised Senate debate as primary nears

Teen student shot at dismissal from Pennsylvania high school

Pennsylvania's three Democratic primary candidates for U.S. Senate are in their third televised debate in a week as the pace of spending is picking up. Tuesday night's debate in Lancaster between John Fetterman, Katie McGinty and Joe Sestak comes two weeks before the April 26 election to determine the party's challenger to Republican U.S. Sen. Pat Toomey. The first questions probed the candidates on international trade deals, their independence, the nuclear accord with Iran and ISIS. Fetterman is the three-term mayor of Braddock, Sestak is a retired Navy rear admiral and former two-term congressman and McGinty has held high-level posts in state and federal government. Total spending in the Democratic primary campaign will likely pass $9 million. Sestak is leading polls. The debate is being broadcast live by WGAL-TV in Lancaster.
