Fetterman is a dead man walking.
He’s already polling over 50%. Unless something happens to damage Fetterman’s popularity, it doesn’t matter if Oz gets 100% of the undecided vote with those kinds of numbers. Oz’s negatives were sky high with even a majority of Republicans disapproving of him in the primary. He should have come straight out of the gate pushing hard to reverse those negatives...he did not - his opponent has already defined him, and his opponent was able to define himself. Many races are won or lost during the summer. Oz did exactly what he needed to do in order to lose it.
