HARRISBURG (AP) – Jeff Bartos is formally launching his campaign for PA’s upcoming open U.S. Senate seat, the highest-profile Republican candidate so far to run for the seat. Bartos was the GOP’s nominee for lieutenant governor in 2018. He was seriously considering a run and filed paperwork to run last month. Today, the suburban Philadelphia real estate investor and longtime GOP fundraiser updated his campaign website to say that he is running. The Montgomery County resident is playing up his work over the past year as a co-founder of the PA 30 Day Fund, a non-profit that distributed forgivable loans to PA small businesses struggling through the pandemic.
