The election itself has been certified. Period. The certification can be amended and changed, but the election has already been certified. Period. Rossi is the Governor-Elect, no matter how much you'd like to believe otherwise.
Not true. State law allows for a machine recount and then a hand recount if requested and paid for. If the SoS wants to rush a certification before all the recounts mandated by law occur, they do not invalidate or cancel the other counts. The certification is of a total from a single count.
