PHILADELPHIA — It's good to be a front-runner. Or just incredibly wealthy.
New financial reports filed Friday reveal in detail how Mehmet Oz and David McCormick, the leading Republican candidates in Pennsylvania's U.S. Senate race, have spent a combined $18 million from their own personal fortunes to fuel their campaigns and make it the most expensive primary election in the country.
The reports, showing campaign finances through March 31, offer the first in-depth look at Oz's campaign funding, and the first look of any kind at McCormick's because he joined the race in January and didn't have to file previous disclosures.
