I could see Raphael Warnock making enough inroads with white evangelicals which could lead to some closer than normal results in some solid conservative states (although he'd likely still lose them by 50 points rather than the nearly 60 points that Trump won them by). Perhaps someone like Padilla or Gallego would be his VP which would explain his strong performance in the Sun Belt, while he'd win the Rust Belt due to Trump fatigue.
Warnock is pro choice.
1. Not all evangelicals are pro-life, especially younger ones.
2. I assumed that him being a pastor would boost him with that group, albeit slightly.
