No, you are missing the point. Hillary and the Dems blame Jill Stein for losing the election, especially in key states like MI, WI, and PA. Hillary has branded Stein as a Russian asset. You seem to buy into that argument.
My point is that Trump could claim something similar using the votes cast for Johnson and McMullen. I don’t buy that argument either, although in the case of NeverTrumper McMullen, there is some substance there.
Hillary was a lousy candidate who has has used numerous excuses for why she lost. Jill Stein was one of them. Pure nonsense.
I have no idea how Hillary spoke of Stein; it is her supporters who blamed Stein (the same thing played out in 2000 with Nader).
Trump supporters could - and would - claim something similar if he had lost, but he won anyway.
