In the past 30 days, there has been only one poll showing Biden ahead of Trump in a head-to-head match-up in Pennsylvania but Biden doesn't need any of Haley's voters to blow Trump out. That race won't be close. Pennsylvania is one of the states who used the COVID pandemic as an excuse to most closely duplicate what California did. Trump cannot win there. It doesn't matter how many people in Pennsylvania support Trump because the system in place will not allow Trump or any Republican to win a statewide race there.
John Fetterman had a stroke, couldn't campaign, and was mostly incapacitated but still won under this new system. No Republican, regardless of how popular they are, can win a statewide race for Presidential nomination, Governor, or Senator of Pennsylvania. Statewide elections in Pennsylvania are now only for show.
