Tonight could be the final time that we have the opportunity to see the Republican candidates for U.S. Senate on the debate stage together.

The debate will be held at Grove City College, located about an hour north of Pittsburgh, beginning at 8 p.m. and will be televised by Newsmax.

Mehmet Oz, the celebrity surgeon, and Dave McCormick, the former hedge fund CEO, will both be in attendance, as will conservative commentator Kathy Barnette, former ambassador Carla Sands and businessman Jeff Bartos.

Greta Van Susteren will serve as the moderator, while KDKA radio host Rick Dayton will also participate.

Oz and McCormick have led the race, according to recent polls, and this may be the last chance to make their case to a large audience. It is also most likely the final opportunity for the remaining three candidates to make a dent in their deficits and rally support.

Last time the quintet met in Harrisburg, the dominant theme was that of former president Donald Trump’s endorsement of Oz. Whether it was Oz repeatedly mentioning the endorsement or the others making their case as the “America First” candidate, the subject was regularly put front and center.

Tonight, it will be abortion rights, following the leak of a draft Supreme Court opinion on the future of Roe v. Wade.

While the opinion of a U.S. Senator will not have the same impact on the Keystone State as that of the governor, Pennsylvanians will still want to hear the candidates’ stances straight from them vs. a TV ad.

As a “#notOz campaign begins to emerge from Republican leaders in the state, it will also be interesting to hear the other contenders stake their position as the option to those who are tired of the Oz-McCormick show. Barnette and Sands may provide some fireworks, while Bartos will try to make headway with his “Main Street” message.
