We, as Democrats, do not have to accept Platner as the nominee. Dems have shown they are very skilled at overturning the results of a primary. I have already emailed Slotkin and Peters about Platner. Just waiting on George Clooney to weigh in. Dems can also support a write in campaign for Costello. There is also a path to a majority in the senate without Maine. I think even if Platner wins, Dems will need a buffer as he has never shown previously to be a progressive.
