There's a competing negative ad on McCormick from a different PAC.
It could be Dem/liberal PACs causing mischief, but my guess would be one backs Oz and the other McCormick. Those two are battling it out in the media.
McCormick's ad are far superior to the ones Oz is running. Oz' spots are bland and generic "outsider" ones. You can tell they are designed from the "Youngkin formula".
McCormick who actually was born and raised in Pennsylvania and whose father was president of Bloomsburg University and chancellor for the Pennsylvania State System of Higher Education, has far superior and engaging ads. They reasonate, imho, with many Pennsylvanians. The one showing the banner hanging in the Bloomsburg high school gym with his wrestling acccomplishments is pitch perfect. Wrestling is huge in Pennsylvania and could get him votes on that criteria alone.
These two are sucking all the air out of the room and I expect the primary to be between them. Further, I expect McCormick to win.
