You have created a Clinton/Trump state in FL. Upstate NY and expanded Delaware are Trump/Biden states.
The first sheet in the xlsx document is nonsensical and incomprehensible, claiming changes in Georgia, Arizona, and Nevada despite not doing anything with those states. Michigan has become more Democratic while Wisconsin has not become more Republican enough to flip. Virginia is unclear: I failed to make this map in KHW because in 4 years he still hasn't figured out how I can select independent cities, but it's clearly a very close state.
In the Senate, Upstate NY and Delaware are potential targets for Republicans to have one seat, and Virginia very likely has one or both R senators. Democrats compensate because Bill Nelson survives in Florida
GA, AZ, NV were indeed not altered; but they appear, because they would be the first Trump-targets (with GA being - instead of WI - the TippingPoint-state).
It surprised me, how safe rest-PA would be despite Pittsburgh being still a part of it.
