PA is the lynch pin. All scenarios require Trump to take PA. The greatest and most obvious fraud occurred in PA. Then we need two others, either WI, MI, GA, AZ and/or NV.
trump has 232 EVs. he needs 270 total or equivalently 38 more than he has now.
PA has 20 EVs
GA has 16 EVs
MI has 16 EVs
WI has 10 EVs
AZ has 11 EVs
NV has 6 EVs
Without PA, trump can get 38 EVs and win in other ways:
GA, MI, WI 42 EVs
GA, MI, NV 43 EVs
GA, WI, AZ, NV 43 EVs
MI, WI, AZ, NV 43 EVs
not counting VA in which fraud may also have occurred
