Noted Toomey voter PittsburghSteel will eventually return to his right-wing roots and stan for Candace Owens in 2024.
To be fair, Bloomberg's (noted Democrat) Super PAC dumped millions to save Toomey in 2016, and I think Gabby Giffords' PAC also spent a lot for him, because of the Manchin-Toomey bill. Anyways, it's perfectly possible that PittsburghSteel is the stereotypical Romney/Clinton voter and has swung solidly Democratic.
An actual good candidate is SuccDem (forgot his Atlas username, but he has an account here)
