When you're running for President of all 50 states that's kind of on you to submit election materials to all 50 states. What I love is that the real moral of the story here is that Alaskans did their job and asked for the correct information, Trump and Johnson didn't reply because our electoral votes are insignificant so who cares and we want to get mad at our fellow Alaskans instead of being angry that these campaigns discounted us. 
This has happened before. Everyone here did their job. The Trump and Johnson campaigns dropped the ball. This isn't a conspiracy, it's just laziness on the part of the candidates.
