HARRISBURG, Pa. (AP) — David McCormick, CEO of one of the world’s largest hedge funds and a former senior official in President George W. Bush’s administration, is accumulating support from longtime party fundraisers and officials in Pennsylvania even before he has formally announced his candidacy for U.S. Senate.

Christine Toretti, Pennsylvania’s longtime Republican national committeewoman, and former state party chair Rob Gleason are among McCormick’s backers, as are fundraisers Pat Deon and Bill Sasso.

Whether McCormick’s high-level support will translate into victory in the May 17 primary election remains to be seen.

McCormick, 56, is preparing to enter a Republican primary field that is newly in flux with the exit of former President Donald Trump’s endorsed candidate, Sean Parnell, and the entrance of Mehmet Oz, who carries unrivaled name recognition as the host of daytime TV’s “Dr. Oz Show.”
